Also , For sandbox when I did a fresh git clone and tried running job, found that global-jjb folder is empty which normally has following files which are needed to build job:
/home/builders/builder/global-jjb#ls
check_jjb_version.py info-schema jjb README.md requirements.txt yamllint.conf
docs jenkins-admin jjb-compare-xml.sh releasenotes shell yaml-verify-schema.py
ensure-documented.sh jenkins-init-scripts license-header.txt relnotes tox.ini
So to solve this I copied global-jjb folder from old builder repo which I had cloned on Monday, can this be reason for job failure in SANDBOX.
In Jenkins anyways they are failing.

Subject: jobs are failing miserable after builder repo rebase
HI All,
Today jobs in Jenkins are failing due to stack failed issue.
I did a git rebase yesterday evening and today morning and ran some job , everything fails at same step as in Jenkins job, ie stacking.
+ cat stack_progress
Stacking Failed
++ cat stack_progress
+ stacking_status='Stacking Failed'
+ '[' 'Stacking Failed' == 'Still Stacking' ']'
+ '[' 'Stacking Failed' == 'Stacking Failed' ']'
+ echo 'node 1 10.30.170.9: stacking has failed'
node 1 10.30.170.9: stacking has failed
+ exit 1
Regards
Jaya
