Customer reported that when running the columnstoreClusterTester script for non-root install on a multi-node system, the test for /dev/shm on remote node passed, but the script was prompting saying a test failed.

Looking at the code, the function checkRemoteDir is not initializing the pass variable to true like other functions, thus causing the error.

Here is output from customer with bash -x
