Hi Team,

I am facing following issue(error) to start region and master servers. Anyone is having any idea on this.

Hi @CK_c Can you check is /tmp mounted with "noexec" flag

You can run below commands and see if it works

# mount | grep /tmp

Re-mount the same with exec flag:

# mount -o remount,exec /tmp

Hi @Scharan, Thank you so much for your quick reply, the "noexec" flag was available for /tmp, after remounting with exec issue resolved.
