[jira] [Commented] (SOLR-12524) CdcrBidirectionalTest.testBiDir()
regularly fails
[ https://issues.apache.org/jira/browse/SOLR-12524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16525512#comment-16525512 ]
Christine Poerschke commented on SOLR-12524:
--------------------------------------------
With some patience the failure is relatively easily reproduced via beasting e.g.
{code}
cd solr/core
ant beast -Dtests.asserts=true -Dbeast.iters=100 -Dtestcase=CdcrBidirectionalTest 2>&1 | tee log.log
{code}
Attached patch proposes to add id info in the assertion error, to make it e.g.
{code}
[beaster] > Caused by: java.lang.AssertionError: 1604455449289031680 != 1604455449282740224
{code}
I've had a good go at trying to learn more about this area of the code but no luck so far in trying to figure out when and how this assertion is hit.
