huaxiangsun 253692cccd HBASE-24073 [flakey test] client.TestAsyncRegionAdminApi messed up compaction state. (#1414)
Addendum:
  For major compaction test, set hbase.hstore.compaction.min to a big number to
  avoid kicking in minor compactions, which will pollute compaction state and
  sometimes, cause major compaction cannot happen.

Bharath Vissapragada 4d1309b6c4 HBASE-24075: Fix a race between master shutdown and metrics (re)init
JMXCacheBuster resets the metrics state at various points in time. These
events can potentially race with a master shutdown. When the master is
tearing down, metrics initialization can touch a lot of unsafe state,
for example invalidated FS objects. To avoid this, this patch makes
the getMetrics() a no-op when the master is either stopped or in the
process of shutting down. Additionally, getClusterId() when the server
is shutting down is made a no-op.

Simulating a test for this is a bit tricky but with the patch I don't
locally see the long stacktraces from the jira.

hbase-server/src/test/java/org/apache/hadoop/hbase/security/access/TestSnapshotScannerHDFSAclController.java

 thinking that was root of original issue (wasn't but no harm in doing
 this change) Moved out the inner class TestHDFSAclHelper.

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

Nick Dimiduk 678b142da2 HBASE-23932 Minor improvements to Region Normalizer (#1258)
- consolidate checks made by master on behalf of balancer and
   normalizer: deciding if the master is in a healthy state for
   running any actions at all (skipRegionManagementAction). Normalizer
   now does as balancer did previously.
 - both balancer and normalizer make one final check on above
   conditions between calculating an action plan and executing the
   plan. should make the process more responsive to shutdown
   requests.
 - change normalizer to only consider acting on a region when it is in
   the OPEN state. previously we would normalizer attempt to merge a
   region that was already in a MERGING_NEW,MERGING,MERGED state.
 - fix some typos in variable names.
