Ishan Chattopadhyaya updated SOLR-10365:
----------------------------------------
Attachment: SOLR-10365.patch
Here's a patch that fixes this situation.
> Collection re-creation fails if previous collection creation had failed
> -----------------------------------------------------------------------
>
> Key: SOLR-10365
> URL: https://issues.apache.org/jira/browse/SOLR-10365
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Ishan Chattopadhyaya
> Attachments: SOLR-10365.patch
>
>
> Steps to reproduce:
> # Create collection using a bad configset that has some errors, due to which
> collection creation fails.
> # Now, create a collection using the same name, but a good configset. This
> fails sometimes (about 25-30% of the times, according to my rough estimate).
> Here's what happens during the second step (can be seen from stacktrace
> below):
> # In CoreContainer's create(CoreDescriptor, boolean, boolean), there's a line
> {{ zkSys.getZkController().preRegister(dcore);}}.
> # This calls ZkController's publish(), which in turn calls CoreContainer's
> getCore() method. This call *should* return null (since previous attempt of
> core creation didn't succeed). But, it throws the exception associated with
> the previous failure.
> Here's the stack trace for the same.
> {code}
> Caused by: org.apache.solr.common.SolrException: SolrCore
> 'newcollection2_shard1_replica1' is not available due to init failure:
> blahblah
> at org.apache.solr.core.CoreContainer.getCore(CoreContainer.java:1312)
> at org.apache.solr.cloud.ZkController.publish(ZkController.java:1225)
> at
> org.apache.solr.cloud.ZkController.preRegister(ZkController.java:1399)
> at org.apache.solr.core.CoreContainer.create(CoreContainer.java:945)
> {code}
> While working on SOLR-6736, I ran into this (nasty?) issue. I'll try to
> isolate this into a standalone test that demonstrates this issue. Otherwise,
> as of now, this can be seen in the SOLR-6736's
> testUploadWithScriptUpdateProcessor() test (which tries to re-create the
> collection, but sometimes fails).
