Subject Re: full partition handling

Hi Brian,

I'm not sure how it will react; I guess the datanode will report an 
error of no space left on device and fail to serve some requests trying 
to write on the partition that is full.

To solve this issue, you have to manually move files from 
/dfs.datanode.data.dir//current to a different partition. Also you have 
to stop the datanode before this "re-balancing".
