--------------------------------------
In FSDirWriteFileOp.startfile
{code:java}
if (iip.getLastINode() != null)
long ret = FSDirDeleteOp.delete(fsd, iip, toRemoveBlocks,
toRemoveINodes, toRemoveUCFiles,
now()); {code}
if file is already exists we delete file , here we dont have any Quota limit
check
[~shashikant] you are suggesting to check quota limit here ?
> "touchz" command should check quota limit before deleting an already existing
> file

> Here, the "touchz" command failed to create the file as the quota limit was
> hit, but ended up deleting the original file which existed. It should do the
> quota check before deleting the file so that after successful deletion,
> creation should succeed.
