> HBase service check failed consistently because the HBase Master died as it
> was trying to write the WAL and could not find enough good datanodes. The
> service check for HBase was run before the service check for HDFS. There may
> be a situation in which we're not giving enough time for all the DN's to come
> up before the HBase service check is being performed, and if it would make
> more sense to service check HDFS before we service check HBase due to
> dependencies.
> With that said it feels like the RU service check order should be:
> * ZooKeeper
> * HDFS
> * YARN
> * Everything else
