Subject Re: writeAsCsv not writing anything on HDFS when WriteMode set to OVERWRITE
Date Tue, 30 Jun 2015 10:06:01 GMT
Hi Mihail,

have you checked that the DataSet you want to write to HDFS actually
contains data elements? You can try calling collect which retrieves the
data to your client to see what’s in there.
