This test validates the complete multi-tenant HFile v4 splitting workflow: + *

    + *
  1. Setup: Creates table with multi-tenant configuration
    2. + *
  2. Data Writing: Writes large datasets with different tenant distributions
    3. + *
  3. Flushing: Forces memstore flush to create multi-tenant HFile v4 files
    4. + *
  4. Splitting: Tests midkey calculation and file splitting
    5. + *
  5. Verification: Validates split balance and data integrity
    6. + *
+ * + *

The test covers various tenant distribution patterns to ensure proper splitting behavior + * across different real-world scenarios. + */ +@Category(MediumTests.class) +public class MultiTenantHFileSplittingTest { + + @ClassRule + public static final HBaseClassTestRule CLASS_RULE = + HBaseClassTestRule.forClass(MultiTenantHFileSplittingTest.class); + + private static final Logger LOG = LoggerFactory.getLogger(MultiTenantHFileSplittingTest.class); + + private static HBaseTestingUtil TEST_UTIL = new HBaseTestingUtil(); + + private static final byte[] FAMILY = Bytes.toBytes("f"); + private static final byte[] QUALIFIER = Bytes.toBytes("q"); + private static final int TENANT_PREFIX_LENGTH = 3; + + // Track whether we're in the middle of a critical operation + private static volatile boolean inCriticalOperation = false; + + // Test configurations for different scenarios + private static final String[] SINGLE_TENANT = {"T01"}; + private static final int[] SINGLE_TENANT_ROWS = {2000}; + + private static final String[] EVEN_TENANTS = {"T01", "T02", "T03", "T04", "T05"}; + private static final int[] EVEN_ROWS_PER_TENANT = {200, 200, 200, 200, 200}; + + private static final String[] UNEVEN_TENANTS = {"T01", "T02", "T03", "T04"}; + private static final int[] UNEVEN_ROWS_PER_TENANT = {100, 300, 500, 100}; + + private static final String[] SKEWED_TENANTS = {"T01", "T02", "T03", "T04", "T05", "T06"}; + private static final int[] SKEWED_ROWS_PER_TENANT = {50, 50, 800, 50, 25, 25}; + + private static final String[] MANY_TENANTS = new String[20]; + private static final int[] MANY_ROWS_PER_TENANT = new int[20]; + static { + for (int i = 0; i < 20; i++) { + MANY_TENANTS[i] = String.format("T%02d", i + 1); + MANY_ROWS_PER_TENANT[i] = 50; + } + } + + private static final String[] FEW_TENANTS = {"T01", "T02"}; + private static final int[] FEW_ROWS_PER_TENANT = {600, 400}; + + @BeforeClass + public static void setUpBeforeClass() throws Exception { + LOG.info("=== Setting up Multi-Tenant HFile Splitting Test class ==="); + + // Configure test settings BEFORE creating the configuration + Configuration conf = TEST_UTIL.getConfiguration(); + + // Set HFile format version for multi-tenant support + conf.setInt(HFile.FORMAT_VERSION_KEY, HFile.MIN_FORMAT_VERSION_WITH_MULTI_TENANT); + conf.setInt(MultiTenantHFileWriter.TENANT_PREFIX_LENGTH, TENANT_PREFIX_LENGTH); + + // Set smaller region size to make splits easier to trigger + conf.setLong("hbase.hregion.max.filesize", 10 * 1024 * 1024); // 10MB + conf.setInt("hbase.regionserver.region.split.policy.check.period", 1000); // Check every second + + // Use IncreasingToUpperBoundRegionSplitPolicy which allows manual splits + // but still prevents automatic splits if we set the file size high enough + conf.set("hbase.regionserver.region.split.policy", + "org.apache.hadoop.hbase.regionserver.IncreasingToUpperBoundRegionSplitPolicy"); + + // Configure mini cluster settings + conf.setInt("hbase.regionserver.msginterval", 100); + conf.setInt("hbase.client.pause", 250); + conf.setInt("hbase.client.retries.number", 6); + conf.setBoolean("hbase.master.enabletable.roundrobin", true); + + // Increase timeouts for split operations + conf.setLong("hbase.regionserver.fileSplitTimeout", 600000); // 10 minutes + conf.setInt("hbase.client.operation.timeout", 600000); // 10 minutes + + // Ensure the HFile format version is set + LOG.info("Configured HFile format version: {}", + conf.getInt(HFile.FORMAT_VERSION_KEY, -1)); + + // Start mini cluster + LOG.info("Starting mini cluster with multi-tenant HFile configuration"); + TEST_UTIL.startMiniCluster(1); + + // Wait for cluster to be fully ready + LOG.info("Waiting for cluster to be ready..."); + TEST_UTIL.waitUntilAllRegionsAssigned(TableName.META_TABLE_NAME); + + // Verify the configuration persisted after cluster start + int postStartVersion = TEST_UTIL.getConfiguration().getInt(HFile.FORMAT_VERSION_KEY, -1); + LOG.info("HFile format version after cluster start: {}", postStartVersion); + + if (postStartVersion != HFile.MIN_FORMAT_VERSION_WITH_MULTI_TENANT) { + LOG.warn("HFile format version changed after cluster start.

This tool supports all HFile versions (v2, v3, and v4) with version-specific enhancements: + *

    + *
  • HFile v2: Basic file inspection, metadata, block headers, and key/value display
    • + *
  • HFile v3: All v2 features plus tag support and encryption metadata
    • + *
  • HFile v4: All v3 features plus multi-tenant support, tenant section display, + * and enhanced metadata for tenant isolation
    • + *
+ * + *

Key improvements for HFile v4 multi-tenant support: + *

    + *
  • Version-aware block index handling (graceful fallback for v4)
    • + *
  • Enhanced block header display with tenant-aware error handling
    • + *
  • Tenant-specific information display with -t option
    • + *
  • Tenant boundary detection in key/value output
    • + *
  • V4-specific trailer field display (multi-tenant flags, tenant prefix length)
    • + *
  • Tenant isolation considerations (suppressed last key)
    • + *
+ * + *

Usage examples: + * 

+ * # Basic metadata for any HFile version
+ * hbase hfile -m -f /path/to/hfile
+ * 
+ * # Key/value pairs with tenant information (v4 files)
+ * hbase hfile -p -v -t -f /path/to/v4/hfile
+ * 
+ * # Block analysis (works across all versions)

Update MultiTenantFSDataInputStreamWrapper to ensure non-negative offsets and enforce section boundaries during read operations. Refactor AbstractMultiTenantReader to handle tenant index metadata more robustly, including checks for valid prefix lengths and improved logging for section initialization. Introduce a new test for the reseekTo functionality in MultiTenantScanner to ensure compliance with forward-only movement requirements. Additionally, adjust DefaultTenantExtractor to prevent allocation during tenant section ID comparisons, enhancing performance. --- .../MultiTenantFSDataInputStreamWrapper.java | 39 ++- .../io/hfile/AbstractMultiTenantReader.java | 219 +++++++++----- .../io/hfile/DefaultTenantExtractor.java | 26 +- .../io/hfile/MultiTenantHFileWriter.java | 275 +++++++++++------- .../io/hfile/MultiTenantPreadReader.java | 14 +- .../hbase/io/hfile/SectionIndexManager.java | 10 +- .../hbase/io/hfile/TenantExtractor.java | 19 +- .../io/hfile/TenantExtractorFactory.java | 21 +- .../hfile/TestMultiTenantScannerReseekTo.java | 129 ++++++++ .../bucket/TestPrefetchWithBucketCache.java | 4 +- 10 files changed, 537 insertions(+), 219 deletions(-) create mode 100644 hbase-server/src/test/java/org/apache/hadoop/hbase/io/hfile/TestMultiTenantScannerReseekTo.java diff --git a/hbase-server/src/main/java/org/apache/hadoop/hbase/io/MultiTenantFSDataInputStreamWrapper.java b/hbase-server/src/main/java/org/apache/hadoop/hbase/io/MultiTenantFSDataInputStreamWrapper.java index e64e594f84b3..56729371fb1d 100644 --- a/hbase-server/src/main/java/org/apache/hadoop/hbase/io/MultiTenantFSDataInputStreamWrapper.java +++ b/hbase-server/src/main/java/org/apache/hadoop/hbase/io/MultiTenantFSDataInputStreamWrapper.java @@ -79,8 +79,8 @@ public MultiTenantFSDataInputStreamWrapper(FSDataInputStreamWrapper parent, long */ public MultiTenantFSDataInputStreamWrapper(FSDataInputStreamWrapper parent, long offset, long sectionSize, boolean ownsParent) { - // Use test constructor to properly initialize both streams and avoid assertion issues - super(parent.getStream(false), parent.getStream(true));
