Subject Re: Error while writing to HDFS NFS from windows
Date Tue, 11 Nov 2014 04:13:50 GMT
Hi Brandon,

Wasn't trying to update a file. The error came up when I was trying to
copy/create a file on the NFS share from windows.

I have tried all of the steps/settings which were listed in the Hortonworks
NFS setup page, still no dice.
