Sunil G commented on YARN-4371:
-------------------------------
Yes, I missed about below code.
{code}
+ // If one or all applications are not found, throw back exception
+ // to return proper error code.
+ if (reportFailure) {
+ throw new ApplicationNotFoundException("Application doesn't exist in
RM.");
+ }
{code}
Existing {{killApplication}} has the capability to throw exception if app s not
found. And I have kept same code, so we will still print application not found
exception correctly in console with app Ids. However, there can be cases when
all apps which are given to kill are not present in RM. So console will print
the error as we already have it. But we also need to send back a non-zero error
code. For tht, I am rethrowing exception to return proper error code in a FULL
error scenario. In partial success cases, we will return 0/
I could return back error code rather than throwing one again. But we need to
have more if check in below parser code. So the dummy message is only to handle
errorCode.
{code}
} else if (cliParser.hasOption(KILL_CMD)) {
if (args.length < 3) {
printUsage(title, opts);
return exitCode;
}
try{
killApplication(cliParser.getOptionValues(KILL_CMD));
} catch (ApplicationNotFoundException e) {
return exitCode;
}
{code}
> "yarn application -kill" should take multiple application ids

> Currently we cannot pass multiple applications to "yarn application -kill"
> command. The command should take multiple application ids at the same time.
> Each entries should be separated with whitespace like:
> {code}
> yarn application -kill application_1234_0001 application_1234_0007
> application_1234_0012
> {code}
