Vladimir Rodionov commented on HBASE-21149:
-------------------------------------------
Yes, it seems that the reason for a failure is test's time out. I can confirm,
that despite the optimization we have in TestBackupBase, HBase cluster starts
up and shuts down in every unit test we run because, maven launches new JVM per
test class. We need to reuse JVM to shorten execution time.
> TestIncrementalBackupWithBulkLoad may fail due to file copy failure
