Subject Monitoring xceivers
Date Thu, 02 Apr 2009 13:29:57 GMT
Hi, all

       I heard from somebody on the list that the xceivers number
 is actually the number of worker threads of the data node process.

Assuming Java uses native threads we can monitor the number of xceivers
just by ls /proc/<data node pid>/task | wc -l and if it is getting to the limit,
add data  nodes.

Does it make sense?
