Anything else running beside the regionserver or datanodes that would suck resources? When datanodes begin to slow, we begin to see the issue Jean-Adrien's configurations address. Are you uploading using MapReduce? Are TTs running on same nodes as the datanode and regionserver? How are you doing the upload? Describe what your uploader looks like (Sorry if you've already done this).

 I already changed the limit of files descriptors,
Good.

 I'll try
to change the properties:
 <property> <name>dfs.datanode.socket.write.timeout</name>
 <value>0</value>
</property>

<property>
  <name>dfs.datanode.max.xcievers</name>
  <value>1023</value>
</property>

Yeah, try it.

And let you know, is any other prescriptions ? Did i miss something ?

BTW, off topic, but i sent e-mail recently to the list and i can't see it:
Is it possible to delete multiple columns in any way by regex : for example
colum_name_* ?
Not that I know of. If its not in the API, it should be. Mind filing a JIRA?

Thanks Slava.
