Hi,
+1 (non-binding)
I have verified this release candidate on JDK 17.
== 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
On the unit tests, four classes failed, and every one is attributable to
my local
environment, not to the release bits:
- TestShadeSaslAuthenticationProvider, TestSecureRESTServer -
Kerberos/SPNEGO
- TestMutualTlsClientSideNonLocalhost
- TestJul2Slf4j
== On-cluster testing ==
I brought up a pseudo-distributed cluster.
- Shell / basic ops smoke test (DDL + CRUD + disable/enable) - PASS
- Load tests: PerformanceEvaluation and LoadTestTool - PASS (0 write
failures, 0 verification failures)
- Integrity: ITBLL run to 1M nodes: Verify success
== New features spot-checked (this RC) ==
- New shell/tool commands: list_liveservers, list_enabled_tables,
list_disabled_tables, list_unknownservers, truncate_region, hbtop batch
mode - PASS
- Store File Tracking (FILE impl): set per-CF, flushed, and confirmed the
.filelist manifest is written on disk - PASS
- Prometheus metrics endpoint (/prometheus on master and RS) returns 200
with
valid exposition format - PASS
No problem surfaced. +1 (non-binding).
Thanks,
Umesh
