             Summary: TestScannerTimeout fails on snapshot branch
                 Key: HBASE-7502
                 URL: https://issues.apache.org/jira/browse/HBASE-7502
             Project: HBase
          Issue Type: Bug
          Components: test
    Affects Versions: hbase-7290
            Reporter: Himanshu Vashishtha
            Assignee: Himanshu Vashishtha
             Fix For: hbase-7290


TestScannerTimeout#test3686a fails consistently on snapshot branch. This is because there is an increase in the number of watches on the rs znode and its deletion takes more time now. The repercussion is that when test3686a starts, it ensures that there are two regionservers and it counts the aborted regionserver as a live one. While processing, it kills one of its server, and also the znode of the previously aborted server expires. Overall effect is there are no regionservers now, and client hangs.
