Saisai Shao commented on SPARK-15984:
-------------------------------------
Is there any problem? I guess you might set max app attempt to 0, so you will
get such warning log, it is illegal to set 0 for max app attempt, it should be
>= 1.
Here is the yarn code.
{code}
int globalMaxAppAttempts =
conf.getInt(YarnConfiguration.RM_AM_MAX_ATTEMPTS,
YarnConfiguration.DEFAULT_RM_AM_MAX_ATTEMPTS);
int individualMaxAppAttempts = submissionContext.getMaxAppAttempts();
if (individualMaxAppAttempts <= 0 ||
individualMaxAppAttempts > globalMaxAppAttempts) {
this.maxAppAttempts = globalMaxAppAttempts;
LOG.warn("The specific max attempts: " + individualMaxAppAttempts
+ " for application: " + applicationId.getId()
+ " is invalid, because it is out of the range [1, "
+ globalMaxAppAttempts + "]. Use the global max attempts instead.");
} else {
this.maxAppAttempts = individualMaxAppAttempts;
}
{code}
