Subject --driver-memory parameter doesn't work for spark-submmit on yarn?
Date Tue, 31 Mar 2015 20:27:16 GMT
Hi All,

 

Below is the my shell script:

 

/home/hadoop/spark/bin/spark-submit --driver-memory=5G --executor-memory=40G
--master yarn-client --class com.***.FinancialEngineExecutor
/home/hadoop/lib/my.jar s3://bucket/vriscBatchConf.properties 

 

My driver will load some resources and then broadcast to all executors.

 

That resources is only 600MB in ser format, but I always has out of memory
exception, it looks like the driver doesn't allocate right memory to my
driver.

 

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

        at java.lang.reflect.Array.newArray(Native Method)

        at java.lang.reflect.Array.newInstance(Array.java:70)

        at java.io.ObjectInputStream.readArray(ObjectInputStream.java:1670)

        at java.io.ObjectInputStream.readObject(ObjectInputStream.java:370)

        at
com.***.executor.support.S3FileUtils.loadCache(S3FileUtils.java:68)

 

Do I do anything wrong here? 

 

And no matter how much I set for --driver-memory value (from 512M to 20G),
it always give me error on the same line (that line try to load a 600MB java
serialization file). So looks like the script doesn't allocate right memory
to driver in my case?

 

Regards,

 

Shuai
