Re: How should I do to solve this problem that the
executorsofmysparkapplication always is blocked after an executor is lost?
I'm not sure it is caused by memory issue, from the log you pasted, seems
there's no very useful information could conclude that this issue is caused
by memory overflow.
Could you please share your memory size of executor (spark.executor.memory)
and number of executors run on each node.
Another related issue is that if you use too many memory that is not enough
for kernel to work, OS will kill the process silently. But from your log I
don't think it is caused by this.
I guess container_1439803298368_0005_01_000001 is application master, its
exit code 15 means EXIT_EXCEPTION_USER_CLASS. I'm not sure what actual
exception is and what could lead to such exception?
I think you'd better do some more tests to reproduce the issue and identify
the problem, sorry currently I've no idea what is the actual cause.
Thanks
