Concurrent randomwalk fails with unbalanced servers

    Details

      Description

      Not always, but sometimes I am seeing the Concurrent randomwalk test fail with:

      java.lang.Exception: Error running node Concurrent.xml
              at org.apache.accumulo.server.test.randomwalk.Module.visit(Module.java:259)
      ...
      Caused by: java.lang.Exception: Error running node ct.CheckBalance
              at org.apache.accumulo.server.test.randomwalk.Module.visit(Module.java:259)
              at org.apache.accumulo.server.test.randomwalk.Module.visit(Module.java:251)
              ... 8 more
      Caused by: java.lang.Exception: servers are unbalanced!
              at org.apache.accumulo.server.test.randomwalk.concurrent.CheckBalance.visit(CheckBalance.java:74)
              at org.apache.accumulo.server.test.randomwalk.Module.visit(Module.java:251)
              ... 9 more
      

      In one case, the 15-minute allowance for balancing extended to a prior run of Concurrent.xml within the same overall test run. In another case, the time span begins at a point when HDFS failed to contact a datanode.
