Installation failed in Replication Distribution command

ColumnStore postConfigure install fails when setting up the MariaDB replication.
Didn't happen on a binary or rpm distribution install, did happen on a yum non-distribution install.
And system was configured with ssh keys between the pm and um nodes, both ways

----- Starting MariaDB ColumnStore on local server -----

MariaDB ColumnStore successfully started

MariaDB ColumnStore Database Platform Starting, please wait ............ DONE

System Catalog Successfully Created

Run MariaDB ColumnStore Replication Setup..
ERROR: Error return in running the MariaDB ColumnStore Master DB Distribute, check /tmp/master-dist*.logs on um1

MariaDB ColumnStore Replication Setup Failed, check logs

IMPORTANT: Once issue has been resolved, rerun postConfigure

Here is the bug, the password ssh should show up here in this command that is outputted to the debug log:

cmd = /usr/local/mariadb/columnstore/bin/rsync.sh 10.128.0.3 /usr/local/mariadb/columnstore 1 > /tmp/master-dist_pm1.log

here is the example when a binary or rpm distributed install works

cmd = /usr/local/mariadb/columnstore/bin/rsync.sh 10.128.0.3 ssh /usr/local/mariadb/columnstore 1 > /tmp/master-dist_pm1.log

This error was reported by a customer and diagnosed by development on customer system. Have reproduced the problem in house.

So at this time, dont know if its a yum issue or a non-distributed install issue. further testing is required
