> In hadoop-functions.sh in the hadoop_basic_init function there is this initialization
of HADOOP_SSH_OPTS:
> {noformat}
> HADOOP_SSH_OPTS=${HADOOP_SSH_OPTS:-"-o BatchMode=yes -o StrictHostKeyChecking=no -o ConnectTimeout=10s"}
> {noformat}
> I believe this parameter substitution is a bug.  While most of the environment variables
set in the function are generally required for functionality (HADOOP_LOG_DIR, HADOOP_LOGFILE,
etc.) I don't believe HADOOP_SSH_OPTS is one of them.  If the user wishes to set HADOOP_SSH_OPTS
to an empty string (i.e. HADOOP_SSH_OPTS="") they should be able to.  But instead, this is
requiring HADOOP_SSH_OPTS to always be set to something.
> So I think the 
> {noformat}
> ":-"
> {noformat}
> in the above should be
> {noformat}
> "-"
> {noformat}
> Github pull request to be sent shortly.
