[jira] [Updated] (SOLR-9647) CollectionsAPIDistributedZkTest got
stuck, reproduces failure
[ https://issues.apache.org/jira/browse/SOLR-9647?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mikhail Khludnev updated SOLR-9647:
-----------------------------------
Attachment: SOLR-9647.patch
[^SOLR-9647.patch] addresses a case when CollectionsAPIDistributedZkTest.testCollectionsAPIAddRemoveStress() tries to spawn too many cores, it hangs and flood heap up to OOME. The reasons are:
* when many cores register at mbean server, all of them hangs on some synchronized policy check inside jmx.
* default version buckets are huge by default, but that method even doesn't send updates.
This patch introduces {{solrconfig-slim.xml}} in {{stressconf}} cloud configset without jmx and with trimmed version buckets. It doesn't address the speculations in the comment above.
One more change has been required: there is a code branch: pick up the only existing configSet if there is no one specified explicitly. But testCollectionsAPIAddRemoveStress now requires an alternative configSet that's why it's skipped with %50 prob.
Is it worth to commit?
