Looks good. I remember there was some issue with a particular version of
zookeeper where the command line argument to zkcli was not being processed,
hence the echo approach was used instead. This should work.
> dcscheck doesn't return while invoking by REST call 'dcs/summary'

> Project: Apache Trafodion
> Issue Type: Bug
> Components: dcs
> Reporter: Eason Zhang
> Assignee: Eason Zhang
>
> When a REST 'get' request 'dcs/summary' is invoked, it will call 'dcscheck'
> to get the dcs master info, but in some specific cases, the 'dcscheck'
> command will never return a value, so REST server hangs, it cannot receive
> any other REST requests any more.
> The reason why 'dcscheck' doesn't return is that it calls the zookeeper CLI
> using pipe like this:
> echo “ls $dcsznode” | $DCS_INSTALL_DIR/bin/dcs zkcli > $dcstmp
> Modify it to not using pipe can solve this issue.
