Sangjin Lee commented on YARN-5071:
-----------------------------------
Regarding #2, I don't think java 8 would be an issue, but things like updated
dependencies or changed hadoop-common APIs would be a problem. In principle, I
don't think this is really a HBase problem at the moment as 3.0.0 has not been
released yet.
> address HBase compatibility issues with trunk

> Key: YARN-5071
> URL: https://issues.apache.org/jira/browse/YARN-5071
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Affects Versions: YARN-2928
> Reporter: Sangjin Lee
> Assignee: Sangjin Lee
> Priority: Critical
>
> The trunk is now adding or planning to add more and more
> backward-incompatible changes. Some examples include
> - remove v.1 metrics classes (HADOOP-12504)
> - update jersey version (HADOOP-9613)
> - target java 8 by default (HADOOP-11858)
> This poses big challenges for the timeline service v.2 as we have a
> dependency on hbase which depends on an older version of hadoop.
> We need to find a way to solve/contain/manage these risks before it is too
> late.
