Hi HBase developers,
I'd like to request a review for HBASE-30099: JIRA: https://issues.apache.org/jira/browse/HBASE-30099 Pull request: https://github.com/apache/hbase/pull/8483 The PR has been open since July 19 and has not received a review yet. The forked GitHub Actions workflows also appear not to have started and may still require approval from someone with write access. The issue is a RegionServer startup race. The RPC server can accept a GetBootstrapNodes request before preRegistrationInitialization() assigns bootstrapNodeManager, causing HRegionServer#getBootstrapNodes to throw an NPE. The patch: * returns an empty iterator before BootstrapNodeManager initialization; * declares the manager reference volatile for publication to RPC threads; * preserves the existing behavior after initialization; * adds a regression test for the pre-initialization call. The targeted Maven test passes: mvn -pl hbase-server -am \ -Dtest=TestBootstrapNodeManager \ -Dsurefire.failIfNoSpecifiedTests=false \ -DskipITs \ test I would especially appreciate feedback on whether an empty bootstrap-node result is the correct behavior during this short startup window. Could a committer please approve the workflows and review the patch when convenient? Thanks, Zhengxuan Ma Pluto [email protected]
