[jira] [Updated] (SPARK-20161) Default log4j properties file should
print thread-id in ConversionPattern

Summary: Default log4j properties file should print thread-id in ConversionPattern (was: Default spark/conf/log4j.properties.template should print thread-id in ConversionPattern)

> Key: SPARK-20161
> URL: https://issues.apache.org/jira/browse/SPARK-20161
> Project: Spark
> Issue Type: Improvement
> Components: Deploy, YARN
> Affects Versions: 2.1.0
> Reporter: Sahil Takiar

> The default log4j file in {{spark/conf/log4j.properties.template}} doesn't display the thread-id when printing out the logs. It would be very useful to add this, especially for YARN. Currently, logs from all the different threads in a single executor are sent to the same log file. This makes debugging difficult as it is hard to filter out what logs come from what thread.
