Review request for Ambari, Andrew Onischuk, Dmitro Lisnichenko, Dmytro Sen, Jonathan Hurley,
Sumit Mohanty, and Sid Wagle.


Bugs: AMBARI-7892
    https://issues.apache.org/jira/browse/AMBARI-7892


Repository: ambari


Description
-------

This is related to AMBARI-7842
WebHCat relies on the following tarballs/jars

|| File || Property ||
| pig-*.tar.gz | templeton.pig.archive |
|hive-*tar.gz | templeton.hive.archive|
| sqoop-*tar.gz | templeton.sqoop.archive|
|hadoop-streaming-*.jar | templeton.streaming.jar|

All of these need to be copied to HDFS, and the name of the file needs to be injected into
the property with the fully qualified path in HDFS.

Testing
-------

Ran ambari-server unit tests,
----------------------------------------------------------------------
Total run:667
Total errors:0
Total failures:0
OK

And verified on cluster using the following steps.

1. Set properties
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env hive_tar_source
                        "/usr/hdp/current/hive-client/hive-{{ component_version }}.{{ hdp_stack_version
}}.tar.gz"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env hive_tar_destination_folder
            "hdfs:///hdp/apps/{{ hdp_stack_version }}/hive/"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env pig_tar_source
                         "/usr/hdp/current/pig-client/pig-{{ component_version }}.{{ hdp_stack_version
}}.tar.gz"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env pig_tar_destination_folder
             "hdfs:///hdp/apps/{{ hdp_stack_version }}/pig/"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env sqoop_tar_source
                       "/usr/hdp/current/sqoop-client/sqoop-{{ component_version }}.{{ hdp_stack_version
}}.tar.gz"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env sqoop_tar_destination_folder
           "hdfs:///hdp/apps/{{ hdp_stack_version }}/sqoop/"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env hadoop-streaming_tar_source
            "/usr/hdp/current/hadoop-mapreduce-client/hadoop-streaming-{{ component_version
}}.{{ hdp_stack_version }}.jar"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev cluster-env hadoop-streaming_tar_destination_folder
"hdfs:///hdp/apps/{{ hdp_stack_version }}/mr/"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev webhcat-site templeton.jar
                 "/usr/hdp/current/hive-webhcat/share/webhcat/svr/lib/hive-webhcat-*.jar"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev webhcat-site templeton.pig.archive
         "hdfs:///hdp/apps/{{ hdp_stack_version }}/pig/pig-{{ component_version }}.{{ hdp_stack_version
}}.tar.gz"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev webhcat-site templeton.hive.archive
        "hdfs:///hdp/apps/{{ hdp_stack_version }}/hive/hive-{{ component_version }}.{{ hdp_stack_version
}}.tar.gz"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev webhcat-site templeton.sqoop.archive
       "hdfs:///hdp/apps/{{ hdp_stack_version }}/sqoop/sqoop-{{ component_version }}.{{ hdp_stack_version
}}.tar.gz"
/var/lib/ambari-server/resources/scripts/configs.sh set localhost dev webhcat-site templeton.streaming.jar
       "hdfs:///hdp/apps/{{ hdp_stack_version }}/mr/hadoop-streaming-{{ component_version
}}.{{ hdp_stack_version }}.jar"

2. Verified properties were saved
http://c6401.ambari.apache.org:8080/api/v1/clusters/dev/configurations?type=cluster-env
http://c6401.ambari.apache.org:8080/api/v1/clusters/dev/configurations?type=webhcat-site

3. Copy changed files
yes | cp /vagrant/ambari/ambari-common/src/main/python/resource_management/libraries/script/config_dictionary.py
                  /usr/lib/ambari-server/lib/resource_management/libraries/script/config_dictionary.py
yes | cp /vagrant/ambari/ambari-common/src/main/python/resource_management/libraries/functions/version.py
                         /usr/lib/ambari-server/lib/resource_management/libraries/functions/version.py
yes | cp /vagrant/ambari/ambari-common/src/main/python/resource_management/libraries/functions/dynamic_variable_interpretation.py
 /usr/lib/ambari-server/lib/resource_management/libraries/functions/dynamic_variable_interpretation.py
yes | cp /vagrant/ambari/ambari-server/src/main/resources/stacks/HDP/2.0.6/services/HIVE/package/scripts/webhcat.py
               /var/lib/ambari-agent/cache/stacks/HDP/2.0.6/services/HIVE/package/scripts/webhcat.py
yes | cp /vagrant/ambari/ambari-server/src/main/resources/stacks/HDP/2.0.6/services/HIVE/package/scripts/params.py
                /var/lib/ambari-agent/cache/stacks/HDP/2.0.6/services/HIVE/package/scripts/params.py
yes | cp /vagrant/ambari/ambari-server/src/main/resources/stacks/HDP/2.1/services/TEZ/package/scripts/params.py
                   /var/lib/ambari-agent/cache/stacks/HDP/2.1/services/TEZ/package/scripts/params.py

4. Check that tarballs are not already in HDFS. If they are, delete them.
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/hive/
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/pig/
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/sqoop/
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/mr/
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -rm -r /hdp/apps/2.2.0.0-974/

5. Before starting WebHCat, check webhcat-site.xml for properties that should be unversioned
less /etc/hive-webhcat/conf/webhcat-site.xml
/ templeton.*archive
/ templeton.*jar

6. Restart WebHCat and verify files are copied to HDFS,
python /var/lib/ambari-agent/cache/stacks/HDP/2.0.6/services/HIVE/package/scripts/webhcat_server.py
START /var/lib/ambari-agent/data/command-102.json /var/lib/ambari-agent/cache/stacks/HDP/2.0.6/services/HDFS
/var/lib/ambari-agent/data/output-102.txt DEBUG /var/lib/ambari-agent/data/tmp
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/hive/
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/pig/
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/sqoop/
[hdfs@c6404 ~]$ hdfs --config /etc/hadoop/conf dfs -ls /hdp/apps/2.2.0.0-974/mr/

7. Verify that webhcat-site.xml has properties with actual values this time.

Check the /etc/hive-webhcat/conf/webhcat-site.xml file again. This time it should have the
properties with the versioned paths.
