This appears to be a stray file that was accidentally committed to the source tree as part of BIGTOP-1284 .
bump Spark version to 0.9.1
remove the unnecessary file (firstname.lastname@example.org)
Thanks yuyun.chen for a quick patch! Much appreciated!
One small nit: for future patches, please format git commit message as:
"BIGTOP-XXX. Jira description"
That was my bad! Sorry about that!
