Review request for Ambari, Dmytro Sen, Jayush Luniya, Mahadev Konar, and Sumit
Mohanty.
Bugs: AMBARI-13251
https://issues.apache.org/jira/browse/AMBARI-13251
Repository: ambari
Description
-------
During the Clients group of RU, restarting hdfs_client changes changes the
symlink /usr/hdp/current/hadoop-client/ from the old version to the new version.
Because the Data Dir Mount History file is stored at
/etc/hadoop/conf/dfs_data_dir_mount.hist and
/etc/hadoop/conf symlinks to /usr/hdp/current/hadoop-client/conf
it means that the file must be copied to the new location.
Multiple clients (HDFS, HBase, Hive, YARN, MapReduce, Pig, Slider, Tez)
actually end up calling
{code}
hdp_select.select("hadoop-client", params.version)
{code}
that changes the symlink, so the first one to be ran during RU must copy the
file. If DataNode is present, it means that HDFS Client is guaranteed to be
there, and from all of those clients it is the first one in the Upgrade Pack.
During a Rolling Downgrade, the file should already exist in the previous
version, and the file is only written to when DataNode is restarted, so we are
ok.

Testing
-------
Tested the alert during RU, and the mount history file was copied to the new
location, so no warnings were generated.
Python unit tests passed,
