------------------------------
Summary: ZKReplicationQueueStorage#setWALPosition should only call
ZKUtil#multiOrSequential when there is at least one ZKUtilOp
Key: HBASE-20269
URL: https://issues.apache.org/jira/browse/HBASE-20269
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
The following test failure is reproducible in master branch:
{code}
testRegionReplicaReplicationIgnoresDroppedTables(org.apache.hadoop.hbase.replication.regionserver.TestRegionReplicaReplicationEndpoint)
Time elapsed: 21.493 sec <<< FAILURE!
java.lang.AssertionError

at
org.apache.hadoop.hbase.replication.regionserver.TestRegionReplicaReplicationEndpoint.testRegionReplicaReplicationIgnoresDroppedTables(TestRegionReplicaReplicationEndpoint.java:372)
{code}
In ZKReplicationQueueStorage#setWALPosition :
{code}
addLastSeqIdsToOps(queueId, lastSeqIds, listOfOps);
ZKUtil.multiOrSequential(zookeeper, listOfOps, false);
{code}
If there is no ZKUtilOp in listOfOps, the call to ZKUtil#multiOrSequential
should be skipped.
