+1 (non-binding)
Thanks for putting the RC together.
*== Release-artifact verification (via dev-support/hbase-vote.sh) ==*
- Signatures verified against KEYS
- Checksums (sha512) match
- Apache RAT license check passes
- Builds from source cleanly (JDK 17)
- Unit tests run
Environment: macOS x86_64, JDK 17 (the supported runtime for 3.0.0).
On the unit tests, every failure I saw was
attributable to my local environment (hostname/loopback resolution,
Kerberos/SPNEGO auth-to-local mapping, mTLS
cert-vs-LAN-IP, and a JDK-distribution artifact), not to the release bits.
*== On-cluster testing ==*
I brought up a pseudo-distributed cluster from the release binary tarball
(HMaster + RegionServer +
HBase-managed ZooKeeper, over the local filesystem) on JDK 17 and
exercised it:
- Shell / basic ops smoke test (DDL + CRUD + disable/enable) - PASS
- Load tests with PerformanceEvaluation and LoadTestTool - PASS
(sequential/random write, random read, scan; LTT write+read-verify
reported 0 failed writes and 0 verification failures at scale)
- Integrity: IntegrationTestBigLinkedList (ITBLL) loop, up to 1,000,000
nodes, Passed
- Load while continuous RS Failover: - PASS
(ServerCrashProcedure split the meta WAL and reassigned all regions;
the test table returned exactly its full row count afterward, cells
intact)
*== New-in-3.0 features (spot-checked on the running cluster) ==*
- StoreFileTracker: change_sft DEFAULT->FILE migrated via
ModifyTableStoreFileTrackerProcedure; the FILE-mode .filelist/
tracker
appeared on disk and "bin/hbase sft -f <tracker>" listed exactly the
HFiles present in the store - PASS
- New shell commands: list_enabled_tables, list_disabled_tables,
list_unknownservers, wal_roll_all, reopen_regions, truncate_region
all behaved correctly (truncate_region cleared just its region) -
PASS
- Prometheus endpoints on master and RegionServer served valid
Prometheus-format metrics - PASS
- Connection URIs: hbase+rpc:// (RpcConnectionRegistry, the 3.0 default)
and hbase+zk:// both connected and listed tables - PASS
- Data tiering: a column family configured with DateTieredStoreEngine
compacted through the date-tiered code path with data intact - PASS
Nothing surfaced that I would consider a blocker. +1 (non-binding).
Thanks,
Umesh
