gate-rally-dsvm-designate-designate failed with exit error 2

I have submitted change in openstack designate for review and observed gate-rally-dsvm-designate-designate FAILURE.

When I checked console log of gate-rally-dsvm-designate-designate, I am seeing below issue -

2016-03-16 20:00:57.720 | Build step 'Execute shell' marked build as failure

In review - gate-rally-dsvm-designate-designate FAILURE in 14m 06s (non-voting)

Have a look at console log for more details - http://logs.openstack.org/72/293672/2/check/gate-rally-dsvm-designate-designate/a27ee6c/console.html

This error is due to "Misuse of shell builtins (according to Bash documentation)" and more details like - Missing keyword or command, or permission problem.

Here, it occurred while moving the file to /opt/stack/logs/ directory!!!

Due to which, gerrit review got "-1" from Jenkins. This causing delay in build & merge procedures and effect releases.

Please fix this issue as below before moving the files to target directory (/opt/stack/logs) -
1) Check whether target directory exist or not. Create it, if doesn't exist!
2) Check whether required permissions available or not. Apply required permissions, if doesn't exist!
3) Once the above two steps are done then initiate the above "mv" operation accordingly.
