Istvan Toth commented on HBASE-28965:
-------------------------------------
If we go the hbase-hadoop3-compat route, then we'd have to duplicate all the
code in the current hbase-hadoop2-compat module, save this single case.
We could move everything currently in hbase-hadoop2-compat to
hbase-hadoop-compat instead, and only use hbase-hadoop2-compat and the new
hbase-hadoop3-compat for the cases where Hadoop2 and 3 are actually
incompatible.
Basically do the same thing we did on master, maybe even backport the same
patch to branch-2.
WDYT [~zhangduo] ?

> Key: HBASE-28965
> URL: https://issues.apache.org/jira/browse/HBASE-28965
> Project: HBase
> Issue Type: Improvement
> Components: Filesystem Integration, hadoop2, io
> Reporter: Duo Zhang
> Priority: Major
>
> The solution before HBASE-28955 can work with hadoop 2.x but after applying
> the changes in HBASE-28955, we can work with hadoop 3.4.x but we can not
> compile with hadoop 2.x then.
> We should find a way to support hadoop 2.x so we can also port the changes to
> branch-2.x as well.
