--------------------------------
lgtm
> 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: 1.0.0, 0.98.10.1
> 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)
