>
> Running {{IntegrationTestTableSnapshotInputFormat}} with the {{BucketCache}}
> enabled results in OOM. The map task is running a sequential scan over the
> region region it opened, so probably it's not benefiting much from a
> blockcache. Just disable blockcache entirely for these scans because it's
> likely the cache config detected is designed for a RS running on a different
> class of hardware than that running the map task.
