[jira] [Commented] (ACCUMULO-3543) ConstraintIT failed
[ https://issues.apache.org/jira/browse/ACCUMULO-3543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14298782#comment-14298782 ]
Keith Turner commented on ACCUMULO-3543:
----------------------------------------
For new test I write, I've adopted the following strategy for things like constraint and table props.
{code:java}
updateConstraint();
while(true){
//keep running test until it succeeds or IT times out
if(checkConstraint())
break;
sleep(100);
}
{code}
> ConstraintIT failed

> In testing 1.6.2-rc3, I have {{ConstraintIT}} fail on me. Being a three-part test, the first two part succeeded, while the third happened to fail.
> Best as I can tell, the watcher for the constraint update on the third table didn't update on the tserver before the test ran. The table

> {noformat}
> The table with id of '3', is the one that failed. The tserver never saw the user-specified constraints before the test ran.
> Add some logic to the test to prevent failures due to this race condition. We have ticket(s) elsewhere for a more generalized "configuration consensus" feature, so I won't restate that here.
