             Summary: [Flakey Tests] Misc fixes and debug; fix BindException in Thrift tests; add waits on quota table to come online; etc.
                 Key: HBASE-24079
                 URL: https://issues.apache.org/jira/browse/HBASE-24079
             Project: HBase
          Issue Type: Bug
          Components: flakies
            Reporter: Michael Stack


Some fixes that have accumulated over last few days.

Fixes for weird NPE on construction of ClientAsyncPrefetchScanner, catches for unexpected, test-killing exceptions in RSProcedureDispatcher and in CompactSplit; add waits on quota table to come on line and regionservers to go down before proceeding; add retry if BindException in thrift tests; disabled a few flakies; etc. Add some debug too.

{code}
    hbase-client/src/main/java/org/apache/hadoop/hbase/client/ClientAsyncPrefetchScanner.java
     Refactor to avoid NPE timing issue referencing lock during Construction.

     Comment

    hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/RSProcedureDispatcher.java
     Refactor. Catch NPE during startup and return it instead as failed initialization.

    hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CompactSplit.java
     Catch IndexOutOfBounds exception and convert to non-split request.

    hbase-server/src/test/java/org/apache/hadoop/hbase/TestCachedClusterId.java
     Make less furious. Make it less flakie.

    hbase-server/src/test/java/org/apache/hadoop/hbase/TestServerSideScanMetricsFromClientSide.java
     Debug. Catch exception to log, then rethrow.

    hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestAsyncRegionAdminApi.java
     Guess that waiting longer on compaction to succeed may help make this
     less flakey.

    hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestFromClientSide3.java
     Be explicit about timestamping to avoid concurrent edit landing
     server-side and messing up test expectation.

    hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestMasterRegistry.java
     Add wait on meta before proceeding w/ test.

    hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestScannersFromClientSide.java
     Be explicit that edits are distinct.

    hbase-server/src/test/java/org/apache/hadoop/hbase/io/hfile/bucket/TestBucketCacheRefCnt.java
     Add @Ignore on RAM test... Fails sporadically.

    hbase-server/src/test/java/org/apache/hadoop/hbase/master/assignment/TestRegionMoveAndAbandon.java
     Add wait for all RegionServers going down before proceeding; was
     messing up RS accounting.

    hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/BalancerTestBase.java
     Make balancer test sloppier; less restrictive; would fail on occasion
     by being just outside test limits.

    hbase-server/src/test/java/org/apache/hadoop/hbase/quotas/TestQuotaObserverChoreRegionReports.java
     Add wait on quota table coming up; helps make this less flakie.

    hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestHRegion.java
     Be explicity about timestamps; see if helps w/ flakie failure.

    hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestRegionReplicas.java
     Catch and ignore if issue in shutdown; don't care if after test.

    hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestRegionServerReportForDuty.java
     Comment.

    hbase-server/src/test/java/org/apache/hadoop/hbase/security/access/TestAccessController.java
     Add retry to see if helps w/ odd failure; grant hasn't propagated?

    hbase-server/src/test/java/org/apache/hadoop/hbase/security/access/TestCellACLWithMultipleVersions.java
     Explicit w/ timestamps so no accidental overlap of puts.

    hbase-thrift/src/test/java/org/apache/hadoop/hbase/thrift/TestThriftHttpServer.java
    hbase-thrift/src/test/java/org/apache/hadoop/hbase/thrift/TestThriftServerCmdLine.java
     Hack to deal w/ BindException on startup.

    hbase-thrift/src/test/java/org/apache/hadoop/hbase/thrift2/TestThrift2ServerCmdLine.java
     Use loopback.

    hbase-thrift/src/test/java/org/apache/hadoop/hbase/thrift2/TestThriftHBaseServiceHandler.java
     Disable flakie test.
