Hi Team, We are using Hadoop version 2.10.2 version and facing below error while starting  server. Due to company security policy no execution permission is enabled on /tmp directory.   Is there any better alternate way by which we can resolve this?  I am new to Hadoop project and help is much appreciated. Many Thanks in advance.
