Chia-Ping Tsai commented on HBASE-17843:
----------------------------------------

It will be a problem only if the timeout happens frequently. I search the 
[jira|https://issues.apache.org/jira/issues/?jql=project%20%3D%20HBASE%20AND%20text%20~%20TestRegionReplicaFailover.java%20ORDER%20BY%20key%20DESC],
 and timeout didn't happen recently. I will close this issue. Please feel free 
to reopen it if you notice that the timeout happens again.

> JUnit test timed out in TestRegionReplicaFailover.java

> Junit test sometimes failed in TestRegionReplicaFailover.java, so I changed
