Anurag Sharma commented on SOLR-6598:
-------------------------------------
I am able to reproducible on windows/cygwin.
Interesting observation, it allows creation creation of 'tEsT' but not 'TEST'
after creation of 'test' collection.

> Solr Collections API, case sensitivity of collection name and

> Key: SOLR-6598
> URL: https://issues.apache.org/jira/browse/SOLR-6598
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.10.1
> Environment: Mac OS X
> Reporter: Alexey Serba
> Priority: Trivial
>
> Solr Collections API returns misleading error when trying to create two
> collections with the same name but with different case on MacOS file system
> (which is case insensitive).

> See {{Lock obtain timed out}} exception. It will be more user friendly to
> check existence of instance dir {{test_shard1_replica1}} and return something
> like "Node A has replica B that uses the same index directory" exception
> (instead of just trying to hijack that existing directory and then
> propagating the inexplicable lock exception that arises as a result).
