I changed this message to timeout due to some concerns in the original PR, but it's also used during early termination - and calling those queries timeouts is misleading.

nit: add @Nullable before File consumerDir.

Since this PR is a bug fix, can you explain in a high level what is the main issue causing the problem and how you fix it? |

Add a javadoc to explain what this directory is about.

LGTM. Thanks for making the hotfix!

Can this ever be null? Currently the abstraction is not very clear, and I don't really see proper null handling. Can we ensure it is always set?

That's a good point, it can be null in the MemoryEstimator path. I think it's probably clearer to set a dummy dir there, and remove the @Nullable annotation for consumerDir
For the realtime flow RealtimeTableDataManager.getConsumerDir() ensures it will not be null.

Seems like you are passing in null as consumerDir here. Do we have a test covering this path? I'd imagine it should throw NPE

We do - it's covered in LuceneMutableTextIndexTest. consumerDir isn't used for the realtime index, and is only used by the LuceneTextIndexCreator initialized during conversion of the realtime segment. Added a comment clarifying this

Addresses #13039. Previously the consumers dir was derived from indexDir, which was not accurate in the case that
pinot.server.instance.consumerDirwas set. This passes consumerDir through to ensure the path is accurate in all cases.Unrelated: also close
Analyzerobjects, and clarify some exception/log.Testing: Unit tests cover, also sanity tested via quickstart w/
pinot.server.instance.consumerDirset.tag:
