Hi Team,

I am submitting the jobs and restarting the job manager and task manager pods..  Log files are generating with the name task manager and job manager.

but job manager & task manager log file size is '0', i am not sure any configuration missed..why logs are not writing to their log files..
##### Task Manager pod###
