Hi All,
The Quick Start page
http://hadoop.apache.org/common/docs/current/quickstart.html contains a
suggestion on how to ssh to localhost w/o a passphrase
Now check that you can ssh to the localhost without a passphrase:
$ ssh localhost
If you cannot ssh to localhost without a passphrase
For some recent discussion, see
https://issues.apache.org/jira/browse/HADOOP-6910

Hello guys,
Over at http://search-hadoop.com we index Hadoop sub-project's mailing
lists, wiki, web site,
source code, javadoc, jira... Including general MLs for Hadoop TLP.
Would the community be interested in a patch that replaces the

Hi Arun,
I think it would be good to have a shared 0.20 Apache security branch.
Since security isn't in 0.21, and the 0.22 release is a some way off
as you mention, this would be useful for folks who want the security
features sooner (and want to use an Apache release).
Thanks,
Tom

Arun,
How much time do you think it would take to have a version of 0.20
with the security features in it ready ? In a different thread, Owen
has started discussing plans around 0.22. Do you think this effort
would affect 0.22 release ?
I do agree that this would be very useful for folks who want

Hi,
I wanted to know why I see running Child processes on my datanodes even though
there is no job running at that time. Are these left over from failed attempts?
Is there anything I can do to keep these clean?
Thanks,
Deepika

Allen, could you please enlist them here again (for the benefit of the
community)? Or, are you referring to only the cluster-wide start scripts?

Use jps to find out pid of the Child.
Then use this to find out which job the Child belongs to:
ps aux | grep

Thanks for your reply.
Some of these child tasks belong to successful jobs. I am wondering why they
are
still hanging there for long finished jobs.

Subject: Re: Child processes
After you obtain pid, you can use jstack to see what the Child process was
doing.
What hadoop version are you using ?

Thanks Ted!
I did a jstack and it seems there is an issue with ehcache that I am using in
the mapper task.
"net.sf.ehcache.cachemana...@57ac3379" daemon prio=10 tid=0x59180800
nid=0x379e in Object.wait() [0x41506000]
java.lang.Thread.State: TIMED_WAITING (on object monitor)
I don't use ehcache.
Did you forget to close CacheManager at the end of your job by any chance ?
