Description

Since Ambari 2.0, Download Client Configs function for any Service results in an exception and error 500.

Clicking on any Service Action -> Download Client Configs results in an error instead of giving the confirmation prompt to save the client configs tar.gz file.

Example:
HDFS Client Configs
Generation of HDFS Client configurations file has failed with 500 error:

org.apache.ambari.server.controller.spi.SystemException: Execution of "ambari-python-wrap /var/lib/ambari-server/resources/stacks/stacks/BigInsights/4.0/services/HDFS/package/scripts/hdfs_client.py generate_configs /var/lib/ambari-server/tmp/HDFS_CLIENT-configuration.json /var/lib/ambari-server/resources/stacks/stacks/BigInsights/4.0/services/HDFS/package /var/lib/ambari-server/tmp/structured-out.json INFO /var/lib/ambari-server/tmp" returned 2. java.lang.Throwable: /usr/bin/python2.6: can't open file '/var/lib/ambari-server/resources/stacks/stacks/BigInsights/4.0/services/HDFS/package/scripts/hdfs_client.py': [Errno 2] No such file or directory

Do you want to try again?

This bug will only manifest if the stack being used does not make use of common-services.
