**Investigation:**
After starting History Server, (which includes adding mapreduce.tar.gz to
HDFS), it complains about HDFS_CLIENT not present.
2017-09-01 21:16:04,194 - Called copy_to_hdfs tarball: mapreduce
2017-09-01 21:16:04,194 - Stack Feature Version Info: Cluster Stack=3.0,
Command Stack=None, Command Version=3.0.0.0-229 -> 3.0.0.0-229
2017-09-01 21:16:04,194 - Tarball version was calcuated as 3.0.0.0-229. Use
Command Version: True
2017-09-01 21:16:04,194 - HDFS_CLIENT is not installed on the host. Skip
copying /usr/hdp/3.0.0.0-229/hadoop/mapreduce.tar.gz
In Ambari-2.5.2 history server host does not have MR client/Hadoop client and
has MR service check passed.
**Solution:**
Seems like Ambari checks if a certain component is installed on the cluster
(like HDFS_CLIENT). However not only HDFS_CLIENT but namenode, datanode,
nfsgateway, journalnode etc.
would include tar.gz. We have to check instead if cluster has a service, but
not that host has a component.
