> In current implementation, bin/hive retrieves HADOOP_VERSION like as follows
> {code}
> HADOOP_VERSION=$($HADOOP version | awk '{if (NR == 1) {print $2;}}');
> {code}
> But, sometimes, "hadoop version" doesn't show version information at the first line.
> If HADOOP_VERSION is not retrieve collectly, Hive or related processes will not be up.
> I faced this situation when I try to debug Hiveserver2 with debug option like as follows 
> {code}
> -Xdebug -Xrunjdwp:trunsport=dt_socket,suspend=n,server=y,address=9876
> {code}
> Then, "hadoop version" shows -Xdebug... at the first line.
