Build tested: 1.4.0-1
This issue occurs only when S3 (both localStorage or S3) storage option (option #4) is selected on a non-distributed installation over multiple nodes. I tested on a 1um2pm stack. The ~/.bashrc file on non-pm1 nodes (um1 and pm2 in my test stack) has the following entry at the end of the file.
This entry is invalid and it cause the following error when the user logs in:
Last login: Tue Sep 10 19:27:28 2019 from 10.0.2.2
-bash: .: /usr/local/mariadb/columnstore/bin/: is a directory
While postConfigure is being executed, I monitored PM2's .bashrc file. The entry seemed to have been inserted from the point where postConfigure tries to start up the stack.
