disable info logging of pig console

September 4, 2012

It's slightly annoying for logging message every time when using pig console like

2012-09-04 07:56:16,158 [main] INFO  org.apache.pig.Main - Apache Pig version 0.10.0 (r1328203) compiled Apr 19 2012, 22:54:12
2012-09-04 07:56:16,159 [main] INFO  org.apache.pig.Main - Logging error messages to: /path/to/cwd/pig_1346712976155.log
2012-09-04 07:56:16,489 [main] INFO  org.apache.pig.backend.hadoop.executionengine.HExecutionEngine - Connecting to hadoop file system at: hdfs://localhost:9000
2012-09-04 07:56:16,713 [main] INFO  org.apache.pig.backend.hadoop.executionengine.HExecutionEngine - Connecting to map-reduce job tracker at: localhost:9001

especially for illustrate and describe, we can't concentrate on the output due to the message.

In order to suppress the message, set an option when launching of pig console.

pig -4 nolog.conf

nolog.conf is very simple which is one line.

log4j.rootLogger=fatal

You can create it like this.

$ echo "log4j.rootLogger=fatal" > nolog.conf
