Subject [jira] [Commented] (HIVE-14332) Reduce logging from VectorMapOperator
Date Tue, 26 Jul 2016 17:11:20 GMT


Siddharth Seth commented on HIVE-14332:

Would it be useful to retain this at the DEBUG level? (or is the information available in
some other way). I'm +1 on either - i.e. the current patch, or moving it to debug. Your call
on whether it is useful for debugging or not.

read type VECTORIZED_INPUT_FILE_FORMAT, vector deserialize type NONE, aliases store_sales
> Lines like this repeat all over the log. This gets really big with a large number of
partitions. 6MB of logs per node for a 30 task query running for 20 seconds on a 3 node cluster.
> Instead of logging this line - can we have a consolidated log / logging only if something
abnormal happens ... or a shorter log message.
