Bizarre as it sounds, it really happens:
- Ubuntu 16.04.1
- sqoop 1.4.6
when I run the command below on my machine which also is a single node hadoop cluster, it (occasionally) kills all hadoop process (!) and terminates the unity session.
sqoop-export --connect jdbc:postgresql://127.0.0.1:5432/db_test --table \
sqoop_quote_6faba4614c --username user --password pass --export-dir \
hdfs://localhost:9000/inputs/id-name.csv --batch -m 1
When this happens, any further attempts consistently terminates the session and you have to just restart the whole machine.
I looked into kernel log and the only lines are:
Aug 19 13:49:02 my-vm gnome-session-binary[2165]: Entering running state
Aug 19 14:34:40 my-vm gnome-session-binary[10961]: Entering running state
Aug 19 14:36:51 my-vm gnome-session-binary[14210]: Entering running state
Anyone has any idea what could be the reason, or where to look to get more debug info?
