Subject [jira] [Created] (HBASE-18069) Fix flaky test TestReplicationAdminWithClusters#testDisableAndEnableReplication

Chia-Ping Tsai created HBASE-18069:
--------------------------------------

             Summary: Fix flaky test TestReplicationAdminWithClusters#testDisableAndEnableReplication
                 Key: HBASE-18069
                 URL: https://issues.apache.org/jira/browse/HBASE-18069
             Project: HBase
          Issue Type: Bug
            Reporter: Chia-Ping Tsai
            Priority: Trivial
             Fix For: 2.0.0, 1.4.0


If we run testDisableAndEnableReplication, we will get the following error message.
{code}
testDisableAndEnableReplication(org.apache.hadoop.hbase.client.replication.TestReplicationAdminWithClusters)
 Time elapsed: 2.046 sec  <<< FAILURE!
java.lang.AssertionError: expected:<1> but was:<0>
        at org.junit.Assert.fail(Assert.java:88)
        at org.junit.Assert.failNotEquals(Assert.java:834)
        at org.junit.Assert.assertEquals(Assert.java:645)
        at org.junit.Assert.assertEquals(Assert.java:631)
        at org.apache.hadoop.hbase.client.replication.TestReplicationAdminWithClusters.testDisableAndEnableReplication(TestReplicationAdminWithClusters.java:160)
{code}
The critical code is shown below.
{code}
    admin1.disableTableReplication(tableName);
    HTableDescriptor table = admin1.getTableDescriptor(tableName);
    for (HColumnDescriptor fam : table.getColumnFamilies()) {
      assertEquals(fam.getScope(), HConstants.REPLICATION_SCOPE_LOCAL);
    }
    table = admin2.getTableDescriptor(tableName);
    for (HColumnDescriptor fam : table.getColumnFamilies()) {
      assertEquals(fam.getScope(), HConstants.REPLICATION_SCOPE_LOCAL);
    }
{code}
Is HTD got from admin2 affected by admin1? I don't think so. We should remove the related
assertion.
