-------------------------------------
Summary: [Flakey Tests] TestFavoredNodeTableImport fails 30% of
the time
Key: HBASE-23737
URL: https://issues.apache.org/jira/browse/HBASE-23737
Project: HBase
Issue Type: Bug
Reporter: Michael Stack
Spent time on TestFavoredNodeTableImport. It fails w/ an NPE when we go to get
favorednodes for one of the regions. It is sporadic. Fails for me locally too
about 30% of the time.
I tried to study where we are going wrong. The balancer is disabled when we
start the cluster up again on FN balancer... but this don't seem to be the
problem.
Looks like laggard Regions taking their time to open means they don't show in
the global list of favored nodes when the checking runs. Adding a wait till no
RIT seems to stabilize the test.
