Description

From https://builds.apache.org/view/G-L/view/HBase/job/HBase-TRUNK/2410/artifact/trunk/target/surefire-reports/org.apache.hadoop.hbase.client.TestAdmin.txt :

testEnableTableRoundRobinAssignment(org.apache.hadoop.hbase.client.TestAdmin)  Time elapsed: 4.345 sec  <<< ERROR!
java.lang.IllegalArgumentException: Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

This was due to:

    HTable metaTable = new HTable(HConstants.META_TABLE_NAME);

A few lines above, we have the correct usage:

    HTable ht = new HTable(TEST_UTIL.getConfiguration(), tableName);
