Alexey Kudinkin updated HUDI-5238:
----------------------------------
Priority: Critical (was: Major)
> Hudi throwing "PipeBroken" exception during Merging on GCS
> ----------------------------------------------------------
>
> Key: HUDI-5238
> URL: https://issues.apache.org/jira/browse/HUDI-5238
> Project: Apache Hudi
> Issue Type: Bug
> Affects Versions: 0.12.1
> Reporter: Alexey Kudinkin
> Assignee: Alexey Kudinkin
> Priority: Critical
> Labels: pull-request-available
> Fix For: 0.13.0
>
>
> Originally reported at [https://github.com/apache/hudi/issues/7234]
> -------
>
> Root-cause:
> Basically, the reason it’s failing is following: # GCS uses
> PipeInputStream/PipeOutputStream comprising reading/writing ends of the
> “pipe” it’s using for unidirectional comm b/w Threads
> # PipeInputStream (for whatever reason) remembers the thread that actually
> wrote into the pipe
> # In BoundedInMemoryQueue we’re bootstrapping new executors (read, threads)
> for reading and _writing_ (it’s only used in HoodieMergeHandle, and in
> bulk-insert)
> # When we’re done writing in HoodieMergeHelper, we’re shutting down *first*
> BIMQ, then the HoodieMergeHandle, and that’s exactly the reason why it’s
> failing
>
> Issue has been introduced at [https://github.com/apache/hudi/pull/4264/files]
