Steve Loughran updated HADOOP-7705:
-----------------------------------
Attachment: HADOOP-7705.patch
updated version with ISO formatted date included. This makes it easier for
people to read, and the caching in Log4J's ISO8601 formatter reduces generation
overhead.
The output of the log now looks like
{code}
{"name":"test","time":1318429136789,"date":"2011-10-12
15:18:56,789","level":"INFO","thread":"main","message":"test message"}
{code}
> Add a log4j back end that can push out JSON data, one per line

> Project: Hadoop Common
> Issue Type: New Feature
> Components: util
> Affects Versions: 0.23.0, 0.24.0

> If we had a back end for Log4j that pushed out log events in single line JSON
> content, we'd have something that is fairly straightforward to machine parse.
> If: it may be harder to do than expected. Once working HADOOP-6244 could use
> it.
