> Not always, but sometimes I am seeing the Concurrent randomwalk test fail with:
> {noformat}
> 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!

> 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.
