Kousuke Saruta created HIVE-5315:
------------------------------------

             Summary: bin/hive should retrieve HADOOP_VERSION better way.
                 Key: HIVE-5315
                 URL: https://issues.apache.org/jira/browse/HIVE-5315
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.11.0
            Reporter: Kousuke Saruta
             Fix For: 0.11.1


In current implementation, bin/hive retrieve 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 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.
