Bill Havanki created ACCUMULO-2198:
--------------------------------------
Summary: Concurrent randomwalk fails with unbalanced servers
Key: ACCUMULO-2198
URL: https://issues.apache.org/jira/browse/ACCUMULO-2198
Project: Accumulo
Issue Type: Bug
Components: test
Affects Versions: 1.4.4
Reporter: Bill Havanki
Assignee: Bill Havanki
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

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.
