Review request for Ambari and Vitalyi Brodetskyi.
Bugs: AMBARI-9618
https://issues.apache.org/jira/browse/AMBARI-9618
Repository: ambari
Description
-------
Add checks in Ambaripreupload.py so that there is minimum chances of tarball
uploads in parallel.
We should add the following checks in:
if dir exists wasb:///hdp/apps/{{ hdp_stack_version }}/mapreduce/:
copy_tarballs_to_hdfs("/usr/hdp/current/hadoop-client/mapreduce.tar.gz",
"wasb:///hdp/apps/{{ hdp_stack_version }}/mapreduce/",
'hadoop-mapreduce-historyserver', params.mapred_user, params.hdfs_user,
params.user_group)
copy_tarballs_to_hdfs("/usr/hdp/current/sqoop-client/sqoop.tar.gz",
"wasb:///hdp/apps/{{ hdp_stack_version }}/sqoop/",
'hadoop-mapreduce-historyserver', params.mapred_user, params.hdfs_user,
params.user_group)
We should do this with all copy tarballs to hdfs in the file - meaning checks
if the directories exist and then only copy the tarballs.
The reason for doing this is so that when Ambari is doing the install/upload
tarballs there is less chances of the ambaripreupload.py script creating a
race condition on tarball upload.
