This issue is observed when there is a custom TMP variable configured in the etc/das-env.sh file.

Cause

This is a configuration issue. Specifically, the TMP variable configured in etc/das-env.sh must be an existing valid path in the file system.

This issue is observed when the TMP variable is configured to a path that does not exist. By default, this variable is set to /tmp which exists by default on most Unix/Linux environments.

Solution

To resolve this issue, ensure that the configured path for the TMP variable in the etc/das-env.sh file exists on the file system.

Additionally, ensure that the user account that is used to start the Datameer process has read and write privileges to the configured TMP directory.
