Hi Arun, I stopped my application, then restarted my hbase (which include hadoop). After that I start my application. After one evening, my /tmp/hadoop-root/mapred/local/archive goes to more than 1G. It does not work.
Is this the right place to change the value? "local.cache.size" in file core-default.xml, which is in hadoop-core-1.0.3.jar Thanks, Jane From: Arun C Murthy [mailto:a...@hortonworks.com] Sent: Wednesday, April 10, 2013 2:45 PM To: user@hadoop.apache.org Subject: Re: How to configure mapreduce archive size? Ensure no jobs are running (cache limit is only for non-active cache files), check after a little while (takes sometime for the cleaner thread to kick in).

It is not in mapred-default.xml. I updated the value in file default.xml and changed the value to 500000. This is just for my testing purpose. However, the folder /tmp/hadoop-root/mapred/local/archive already goes more than 1G now. Looks like it does not do the work. Could you advise if what I did is correct? <name>local.cache.size</name> <value>500000</value> Thanks, Xia From: Hemanth Yamijala [mailto:yhema...@thoughtworks.com] Sent: Monday, April 08, 2013 9:09 PM To: user@hadoop.apache.org<mailto:user@hadoop.apache.org> Subject: Re: How to configure mapreduce archive size? Hi, This directory is used as part of the 'DistributedCache' feature. (http://hadoop.apache.org/docs/r1.0.4/mapred_tutorial.html#DistributedCache). There is a configuration key "local.cache.size" which controls the amount of data stored under DistributedCache. The default limit is 10GB. However, the files under this cannot be deleted if they are being used. Also, some frameworks on Hadoop could be using DistributedCache transparently to you. So you could check what is being stored here and based on that lower the limit of the cache size if you feel that will help. The property needs to be set in mapred-default.xml.

There is some mapreduce job running on my server. After some time, I found that my folder /tmp/hadoop-root/mapred/local/archive has 14G size. How to configure this and limit the size? I do not want to waste my space for archive. Thanks, Xia -- Arun C. Murthy Hortonworks Inc. http://hortonworks.com/
