---------------------------------
Status: Patch Available (was: Open)
Thanks Hairong. Yes, this only improves log message. I'm no sure how such
patches are handled. I making this patch available and you can change it to
'open' after the patch is submitted.

> One of the datanodes has one full partition (disk) out of four. Expected
> behaviour is that datanode should skip this partition and use only the other
> three. HADOOP-990 fixed some bugs related to this. It seems to work ok but
> some exceptions are still seeping through. In one case there 33 of these out
> 1200+ blocks written to this node. Not sure what caused this. I will submit a
> patch to the prints a more useful message throw the original exception.
> Two unlikely reasons I can think of are 2% reserve space (8GB in this case)
> is not enough or client some how still says block size is zero in some cases.
> Better error message should help here.
> If you see small number of these exceptions compared to number of blocks
> written, for now you don't need change anything.
