> LoadIncrementalHFiles (during bulk load) restart isn't safe during hfile
> splitting

> Key: HBASE-30501
> URL: https://issues.apache.org/jira/browse/HBASE-30501
> Project: HBase
> Issue Type: Bug
> Reporter: Ujjawal Kumar
> Priority: Major
> Labels: pull-request-available
>
> LoadIncrementalHFiles automatically splits an HFile that crosses region
> boundaries into .bottom and .top files under .tmp and tracks them in an
> in-memory queue. If the invocation
> fails after splitting but before loading—for example, due to the maximum
> HFiles-per-region/family limit—the queue is lost. A new invocation may not
> rediscover .tmp files, while the original HFile may already have been
> deleted.
>
>
>
> Update the retry behavior to preserve the original HFile until the split
> outputs are successfully loaded, or persist and rediscover split outputs
> across invocations. Add tests covering failure after splitting followed by
> a fresh LoadIncrementalHFiles retry.
