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)
