             Summary: Skipping "hbase mapredcp" in hive script for certain services
                 Key: HIVE-15322
                 URL: https://issues.apache.org/jira/browse/HIVE-15322
             Project: Hive
          Issue Type: Improvement
            Reporter: Daniel Dai
            Assignee: Daniel Dai


"hbase mapredcp" is intended to append hbase classpath to hive. However, the command can take some time when the system is heavy loaded. In some extreme cases, we saw ~20s delay due to it. For certain commands, such as "schemaTool", hbase classpath is certainly useless, and we can safely skip invoking it.
