      Description

      I got the following test failure:

      testExceptionFromCoprocessorDuringPut(org.apache.hadoop.hbase.coprocessor.TestRegionServerCoprocessorExceptionWithAbort)  Time elapsed: 0.049 sec  <<< ERROR!
      java.lang.Exception: test timed out after 60000 milliseconds

      This was due to unexpected LeaseException bringing down region server:
