calling hbase shell from bash

Hi,
I use the following in bash:
echo "get '$table', 'row'" | bin/hbase shell

The above is in a loop. Is there a way to expedite execution by not spawning
hbase shell each time ?

Also, how do I set timeout for the above command so that I can have control
over the amount of time my bash script uses ?

Thanks

You'd have to daemonize the shell and then send it commands.  Its
probably possible but I've not tried it.  Use REST server instead?
