Metastore logging

[Marc Hoppins <hp...@gmail.com>]

Hi, All,

Can anyone please give me some help getting metastore logging split off
from the main log file?

The documentation seems to suggest that just creating
metastore-log4j2.properties will begin logging into the log file specified
within but that does not seem to be the case.

I have tried creating metastore-site.xml with no luck.
I have tried hive-metastoresite.xml within similar results.

Frankly, I would have expected something in hive-site.xml along the lines of

<name>hive.metastore.logging.enable</name>
<value>true</value>

to initiate metastore logging as hive.server2.logging.operation.enabled
exists.

We also use (old) cloudera but I believe all the config is stored in a
database as the regular xml files are quite bare but that IS logging to a
main log and metastore log.

Any suggestions would be gratefully received.

Marc

Hi Marc,

If you're running HMS (v4.x) as a standalone instance, you can configure logging via metastore-log4j2.properties. 
You can find a default template under https://github.com/apache/hive/blob/master/standalone-metastore/packaging/src/docker/conf/metastore-log4j2.properties in the Hive source tree. Place it in your conf/ directory on the classpath and adjust as needed.
