{code}
Check the code about client, when AMEndpoint dissconnected, will finish
Application with SUCCESS final status
{code}
override def onDisconnected(remoteAddress: RpcAddress): Unit = {
// In cluster mode or unmanaged am case, do not rely on the disassociated
event to exit
// This avoids potentially reporting incorrect exit codes if the driver
fails
if (!(isClusterMode || sparkConf.get(YARN_UNMANAGED_AM))) {
logInfo(s"Driver terminated or disconnected! Shutting down.
$remoteAddress")
finish(FinalApplicationStatus.SUCCEEDED, ApplicationMaster.EXIT_SUCCESS)
}
}
{code}
Nomally in client mode, when application success, driver will stop and AM loss
connection, it's ok that exit with SUCCESS, but if there is a not work problem
cause dissconnected. Still finish with final status is not correct.
Then YarnClientSchedulerBackend will receive application report with final
status with success and stop SparkContext cause application failed but mark it
as a normal stop.
{code}
private class MonitorThread extends Thread {
private var allowInterrupt = true
override def run() {
try {
val YarnAppReport(_, state, diags) =
client.monitorApplication(appId.get, logApplicationReport = false)
logError(s"YARN application has exited unexpectedly with state $state!
" +
"Check the YARN application logs for more details.")
diags.foreach { err =>
logError(s"Diagnostics message: $err")
}
allowInterrupt = false
sc.stop()
} catch {
case e: InterruptedException => logInfo("Interrupting monitor thread")
}
}
def stopMonitor(): Unit = {
if (allowInterrupt) {
this.interrupt()
}
}
}
