Istvan Toth commented on HBASE-28446:
-------------------------------------
Does building with Hadoop 3.3 by default mean that we drop support for earlier
Hadoop versions ?
Previous HBase versions supported multiple Hadoop versions.

> Project: HBase
> Issue Type: Improvement
> Reporter: Wei-Chiu Chuang
> Priority: Minor
>
> HBASE-21946 used reflection to access the ByteBufferPositionedReadable API
> that's only available in Hadoop 3.3.
> Now that HBase branch-2.6 and above updated hadoop three dependency to 3.3,
> we can get rid of the reflection.
