Duo Zhang updated HBASE-25771:
------------------------------
Component/s: documentation
> Recommend Hadoop 3.x
> --------------------
>
> Key: HBASE-25771
> URL: https://issues.apache.org/jira/browse/HBASE-25771
> Project: HBase
> Issue Type: Task
> Components: documentation
> Reporter: Wei-Chiu Chuang
> Priority: Major
>
> We have this section in the hbase book:
> {quote}
> Hadoop 2.x is recommended.
> Hadoop 2.x is faster and includes features, such as short-circuit reads (see
> Leveraging local data), which will help improve your HBase random read
> profile. Hadoop 2.x also includes important bug fixes that will improve your
> overall HBase experience. HBase does not support running with earlier
> versions of Hadoop. See the table below for requirements specific to
> different HBase versions.
> Hadoop 3.x is still in early access releases and has not yet been
> sufficiently tested by the HBase community for production use cases.
> {quote}
> The Hadoop 2.x development is winding down. 2.10.x will be the last dev
> branch. On the contrary, we've got years of production users on Hadoop 3.x
> already so I think it's time to change our stance.
