We're running 0.20.2 (Cloudera cdh3u4).
What configs are you referring to?

What version of hadoop are you running? Potentially you need configs to protect
the JT that you are missing, those should ensure your hadoop-1.x JT is very
reliable.

Our job tracker has been seizing up with Out of Memory (heap space) errors for

crash I doubled it again to 4GB.
This all seems a bit puzzling to me. I wouldn't have thought that the job
tracker should require so much memory. (The NameNode, yes, but not the job
tracker.)
Just wondering if this behavior sounds reasonable, or if perhaps there might be
a bigger problem at play here. Anyone have any thoughts on the matter?
Thanks,
