> "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.
