Jar files created when invalidate metadata is ran on node running catalog server

ABaaya — Fri, 16 Sep 2022 11:24:28 GMT

Has anyone faced issue with impala catalog server creating jar files and storing it in /tmp dir on the node where impala catalog server is running? Like below.

Everytime i run invalidate metadata on any database, it creates 2 jar files like below and doesnt delete those after it finishes.

These files keep on increarsing and overtime start causing below issue

Query: invalidate metadata
ERROR:
FSError: java.io.IOException: No space left on device
CAUSED BY: IOException: No space left on device

Also resulting in failure of catalog server and impala daemon eventually.

This happens with only one of my cluster. All my clusters are running on same version. No change done recently.

Using CDH 5.8.3, Impala Shell v2.6.0-cdh5.8.3.

Jar files created on running invalidate metadata command.

CDH5.10.2 should have the fix for that specific issue.
