Description

"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.
