Hi, everyone
I have a question about the arg spark.akka.frameSize , it default value is 10m .
I execute the JavaWordCount read data from hdfs , there is a 7G file .
there is a oom error caused by
some task result exceeded Akka frame size .
but when I modify the arg 1G ，2G ， 10G , it show me
ERROR ClusterScheduler: Lost executor 1 on ocnosql84: remote Akka client
shutdown
13/12/24 19:41:14 ERROR StandaloneExecutorBackend: Driver terminated or
disconnected! Shutting down.
Sometimes it show me different error info :
[lh1@ocnosql84 src]$ java MyWordCount spark://ocnosql84:7077
hdfs://ocnosql76:8030/user/lh1/cdr_ismp_20130218 15000 1g 120

13/12/24 19:20:33 ERROR SparkDeploySchedulerBackend: Disconnected from Spark
cluster!
13/12/24 19:20:33 ERROR ClusterScheduler: Exiting due to error from cluster
scheduler: Disconnected from Spark cluster
It seems caused by
LengthFieldBasedFrameDecoder lenDec = new
LengthFieldBasedFrameDecoder(this.client.netty().settings().MessageFrameSize(),
0, 4, 0, 4);
I don't know what's the value of
this.client.netty().settings().MessageFrameSize() and how to calculate this
value .
my spark args :
export SPARK_DAEMON_MEMORY=4000m
export SPARK_MEM=1000m
export SPARK_WORKER_MEMORY=8g
spark.akka.frameSize = 1000 / 2000 / 5000 / 10000 / 15000
spark.executor.memory = 1g
spark.akka.askTimeout = 120
Any help or reply is very appriciated ! Thanks very much
