Hi,

We're about to upgrade our Hadoop cluster - on which we primarily run
HBase - from Hadoop 3.2.4 (HBase 2.5.8) to Hadoop 3.4.1 (HBase
2.5.12).

Is there anything I need to be especially aware of?

Do I need to upgrade to the latest 3.3 before moving on to 3.4? I
didn't find any hints in the documentation - maybe I didn't look hard
enough.

I am of course consulting the overviews and release notes for the
versions in between.


At the same time we are also switching from openjdk-8 to openjdk-17 -
are there any tips for configuration I should follow?



  Thanks,

   Adam
