Replication setup failed when using ssh key and schema sync enabled

Build tested: 1.1.1-1 CS

I am tried to install a 1um2pm stack using ovh physical servers. When postConfigure prompted about "ColumnStore Schema Sync", I answered with y. postConfigure failed with replication setup. The servers used have ssh key setup between pm1 and other nodes.
