Subject namenode grows overtime
Date Wed, 18 Jan 2012 23:23:16 GMT
Hi guys,

we are running Hadoop 0.20.2+228, the namenode process's memory grows
overtime to occupy over 18GB.  However, if I restart the namenode, it only
occupies about 10GB after it is stable.  I am wondering if there is anyway
to figure out what is going on with namenode that causes it to grow very
rapidly and if there are any tools to make the namenode printout some
useful information on what is holding onto that memory.

Thanks,

Felix
