Jian He commented on YARN-5227:
-------------------------------
oh, I misread. I interpreted as "If containerId is specified, appId should be
null".
May be change the message to be something like "ERROR: Both applicationId and
containerId are not specified. One of them must be specified."
For below logic, if both appId and containerId are specified, containerId will
not be interpreted ? Then it will fail
{code}
if (appIdStr != null) {
try {
appId = ApplicationId.fromString(appIdStr);
} catch (Exception e) {
System.err.println("Invalid ApplicationId specified");
return -1;
}
} else {
try {
containerId = ContainerId.fromString(containerIdStr);
appId = containerId.getApplicationAttemptId().getApplicationId();
} catch (Exception e) {
System.err.println("Invalid ContainerId specified");
return -1;
}
}
{code}
