(Updated Feb. 7, 2015, 1:16 a.m.)
Review request for Ambari, Dmitro Lisnichenko, Jonathan Hurley, Nate Cole, Tom
Beerbower, and Yurii Shylov.
Changes
-------
Added unit test.
Bugs: AMBARI-9507
https://issues.apache.org/jira/browse/AMBARI-9507
Repository: ambari
Description
-------
Prepare namenode failed during RU on Ubuntu12, retry does not help.
This is because ru_execute_task.py calls python directly, instead of the python
wrapper that appends several other directories to the PYTHONPATH environment
variable, which is needed by the module imports.
