Which version of spark are you using? You can try changing the heap size
manually by *export _JAVA_OPTIONS=-Xmx5g *
Thanks

Hi,
I just encountered the same problem, when I run a PageRank program which has
lots of stages(iterations)…
The master was lost after my program done.
And, the issue still remains even I increased driver memory.
Have any idea? e.g. how to increase the master memory?
Thanks.
Best,

How many nodes do you have in your cluster, how many cores, what is the
size of the memory?

Hi Arush,
Mine is a CDH5.3 with Spark 1.2.
The only change to my spark programs are
-Dspark.driver.maxResultSize=3g
Hi,
I have a Hidden Markov Model running with 200MB data.
Once the program finishes (i.e. all stages/jobs are done) the program
hangs for 20 minutes or so before killing master.
In the spark master the following log appears.
2015-02-12 13:00:05,035 ERROR akka.actor.ActorSystemImpl: Uncaught
What is your cluster configuration? Did you try looking at the Web UI?
There are many tips here
http://spark.apache.org/docs/1.2.0/tuning.html
Did you try these?

I have 5 workers each executor-memory 8GB of memory. My driver memory is 8
GB as well. They are all 8 core machines.
To answer Imran's question my configurations are thus.
executor_total_max_heapsize = 18GB
This problem happens at the end of my program.
I don't have to run a lot of jobs to see

The important thing here is the master's memory, that's where you're
getting the GC overhead limit. The master is updating its UI to include
your finished app when your app finishes, which would cause a spike in
memory usage.
I wouldn't expect the master to need a ton of memory just to serve the
Increasing your driver memory might help.
Thanks
