Hi HBase devs,

Over the past few years HBase supports the default Hadoop version of 3.2.x
but it also works on Hadoop 3.3.x.

I'm wondering if it makes sense to move the current default hadoop.version
<https://github.com/apache/hbase/blob/master/pom.xml#L800> from 3.2.4 to
3.3.x.

Why?

1. From a stability and security point of view, Hadoop 3.3 is the most up
to date release line. And all HBase tests pass using 3.3.x. There hasn't
been a new Hadoop 3.2.x release for over a year.

2. We have a feature (using HBase on Ozone) that depends on an API in
Hadoop 3.3.6 that is not yet in any 3.2 release line. Moving the default
hadoop version to 3.3.6 will save a lot of hassle.

Thoughts?

Best,
Weichiu
