Description

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.
