Can you please share the logs from your Region Server when it got killed/stopped suddenly so that we can track the events to understand what happened?

Also please check the "/var/log/messages" file, matching the timestamp when your Region Server got killed/stopped.

When you start running your sqoop job that time did you notice the following outputs?
# free -m
# top


To verify if your OS was having enough resources when you started the sqoop job?

This is important because sometimes due to resource unavailability the OS kills some resources.


Example: (just example)

The "/proc/sys/vm/overcommit_memory" settings on the OS can allow OS to kill the applications that are consuming much memory. See:
