[jira] [Commented] (SOLR-11929) TestRecovery failures
[ https://issues.apache.org/jira/browse/SOLR-11929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16424784#comment-16424784 ]
Steve Rowe commented on SOLR-11929:
-----------------------------------
I traced the problem to the {{testReload()}} method being run prior to the other failing test methods; when I comment out its body all tests succeed with all seeds.
The NPE in {{testBuffering()}} is caused by the {{TLOG.state}} metric not being present, apparently because {{UpdateLog.initializeMetrics()}} is never called on core reload.
I've attached a patch that initializes {{UpdateLog}} metrics upon core reload, and this allows all tests to pass with the seeds I have for this problem (another one not listed above: {{F999698B6BBE3431}}, from https://jenkins.thetaphi.de/job/Lucene-Solr-master-MacOSX/4542/ ).
[~ab], can you take a look and see if the patch is doing the right thing here?
