Subject [jira] [Commented] (SOLR-8135) SolrCloudExampleTest.testLoadDocsIntoGettingStartedCollection reproducible failure
Date Thu, 04 Feb 2016 03:23:39 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15131652#comment-15131652
] 

Noble Paul commented on SOLR-8135:
----------------------------------

bq.This feels a little like a band-aid. 
Erick, I'm not trying to make this test pass. This is a more serious issue. A race condition
should not put a core in an unrecoverable error situation. This would cause SolrCloud to lose
replicas randomly. I'm surprised users have not experienced it yet . So, this fix must be
done anyway. 

bq.Tim's comment about a delay suggests that if we waited for the config changes to complete
reloading before continuing the test we'd be OK
That is fine if you wish to just avoid hitting the race condition. But in this case we should
be glad that this test has uncovered a race condition
