Subject [jira] [Commented] (ACCUMULO-2194) Back-to-back Security randomwalk tests fail
Date Wed, 12 Mar 2014 13:37:44 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13931757#comment-13931757

Bill Havanki commented on ACCUMULO-2194:
----------------------------------------

Got this a second time, but different error:

{noformat}
Caused by: org.apache.accumulo.core.client.AccumuloException: User didn't exist when they
should (or
 worse- password mismatch)
        at org.apache.accumulo.server.test.randomwalk.security.TableOp.visit(TableOp.java:62)
        at org.apache.accumulo.server.test.randomwalk.Module.visit(Module.java:251)
{noformat}

The common thread in both cases is that the table user is found to exist when the user was
in fact dropped at the end of the prior run. I'm pretty sure, based on similar issues before,
that it's just that ZK hasn't had time enough to completely absorb the change. (When starting
a new security test, the system user is created but the table user is not, so this is not
a problem for the system user account.) This time here, the time between dropping the user
and the error is just under one second.

> When the Security randomwalk test is run twice in a row by a higher-level test (e.g.,
ShortClean), the second Security test fails relatively quickly. A sample log is attached.
