> optimize 'hbase classpath' cmd in sqenvcom.sh
> ---------------------------------------------
>
> Key: TRAFODION-2806
> URL: https://issues.apache.org/jira/browse/TRAFODION-2806
> Project: Apache Trafodion
> Issue Type: Improvement
> Components: foundation
> Reporter: Eason Zhang
> Assignee: Eason Zhang
> Priority: Minor
>
> Currently, every time we login a new shell with trafodion user, it will
> invoke 'hbase classpath' command to get all hbase libs info, this will slow
> down the login session as well as any 'pdsh' commands.
> An optimization is to cache the output of 'hbase classpath' to a file under
> $TRAF_VAR/hbase_classpath, then sqenvcom.sh will get the hbase lib from this
> file if exists.
