Good catch @merrimanr

When I was testing queries in some other feature branch PR's, I had to
change hdfs permissions for the Storm and Metron users to be able to function
on both the write and read end of things (Storm writing sequence files, MR jobs
reading sequence files and writing them back out to HDFS or local FS). @MohanDV
and @merrimanr Did this work for you without needing to make any additional
changes? metron:metron did not allow pcap topology to write as the Storm user.
