Recommend JSON Library? net.sf.json has memory leak

[Kevin Peterson <kp...@biz360.com>]

We're using JSON serialization for all our data, but we can't seem to find a
good library. We just discovered that the root cause of out of memory errors
is a leak in the net.sf.json library. Can anyone out there recommend a java
json library that they have actually used successfully within Hadoop?

I had discovered a memory leak in net.sf.json as well.  I filed an issue and
it got fixed in the latest release:
http://sourceforge.net/tracker/?func=detail&atid=857928&aid=2063201&group_id=171425

Have you tried the latest version 2.2.3?

I also use Jackson and recommend it.

We've used Jackson(http://jackson.codehaus.org/), which we've found to be easy to use and faster than any other option.  We've also had problems with net.sf in terms of memory and performance.

You can see a performance comparison here: http://www.cowtowncoder.com/blog/archives/2009/02/entry_204.html
