Perché l'applicazione spark non riesce con "executor.CoarseGrainedExecutorBackend: Driver Dissociati"?

Question

Quando eseguire SQL Query tramite scintilla presentare e scintilla-SQL, corrispondente all'applicazione scintilla sempre con errore segue:

15/03/10 18:50:52 INFO util.AkkaUtils: Connecting to HeartbeatReceiver: akka.tcp://sparkDriver@slave75:60697/user/HeartbeatReceiver

e sopra è solo uno degli errori, ho usato "logs filato -l'applicazione application_1425944520319_8102. log" per ottenere l'intero registro di applicazione e schermare l'errore come di seguito:

si può ottenere il file di log da https://www.dropbox.com/s/lf50ger18v3ngtb/application_1425944520319_8102.log?dl=0 se non mi esprimo in modo chiaro.

La rete di slave75 è ok e gli host in tutti i nodi sono configurati correttamente. Qualsiasi risposta aiuterà, grazie!

Answer 1

Infine ho trovato il motivo, perché filato uccidere l'esecutore (contenitore). L'esecutore è sovraccarico della memoria, basta aumentare il valore di spark.yarn.driver.memoryOverhead o spark.yarn.executor.memoryOverhead o entrambi.

Answer 2

Nel mio caso, ho risolvere il problema aumentando il numero di attività parallele che leggere i dati RDD
