Wangda Tan commented on YARN-2980:
----------------------------------
We should make this in 2.8 after YARN-3375 get committed. Marked this to be
blocker since it will cause unnecessary code divergence between trunk/branch-2.
> Move health check script related functionality to hadoop-common

> HDFS might want to leverage health check functionality available in YARN in
> both namenode https://issues.apache.org/jira/browse/HDFS-7400 and datanode
> https://issues.apache.org/jira/browse/HDFS-7441.
> We can move health check functionality including the protocol between hadoop
> daemons and health check script to hadoop-common. That will simplify the
> development and maintenance for both hadoop source code and health check
> script.
> Thoughts?
