---------------------------------------
Summary: TestMasterObserver deleteTable is flaky
Key: HBASE-13179
URL: https://issues.apache.org/jira/browse/HBASE-13179
Project: HBase
Issue Type: Test
Components: test
Affects Versions: 0.98.10.1, 1.0.0
Reporter: Matteo Bertozzi
Assignee: Matteo Bertozzi
Priority: Minor
Attachments: HBASE-13179-v0.patch
TestMasterObserver fails when deleteTable() takes more time to complete the
last steps.
{code}
java.lang.AssertionError: Delete table handler should be called.
at org.junit.Assert.fail(Assert.java:88)
at org.junit.Assert.assertTrue(Assert.java:41)
at
org.apache.hadoop.hbase.coprocessor.TestMasterObserver.testTableOperations(TestMasterObserver.java:1283)
{code}
The problem is the same as the one in createTable() and it is because the sync
version of the Admin operation is not sync, but relies on the last operation on
the server e.g. delete meta.
but the post-operation method of the coprocessor is called after meta is
deleted..
long story short, the client is not really sync and it will be fixed by
HBASE-12439. so for now we should have the same fix we have for createTable
which is using a latch.
(note: there are other tests failing for this reason e.g. AccessController,
NamespaceAuditor, ... but I'll fix them in another patch since we have already
a workaround in TestMasterObserver)
