---------------------------------------------------------------
[~surendrasingh] Thanks for filing this JIRA.
I'm +1 for adding this command, it will be very useful for monitor scripts and
auto test-case scripts.
* Here're my comments for your patch.
{code}
HAServiceProtocol proto = target.getProxy(getConf(), 5000);
{code}
* Would you mind using "rpcTimeoutForChecks" instead of "5000" here?
{code}
catch (IOException e) {
out.println(String.format("%-50s %-10s", target.getAddress(),
"Failed to connect."));
}
{code}
The exception message in {{getAllServiceState}} is ignored, I think it's good
to expose it.
