OK thanks Robert you have been very clear now! :)
just one question, more related on emr than to flink, if i cannot run anything
on the EMR master, then is it useful to allocate a big machine (8 core, 30GB)
on it? I thought it was the jm but it is not

Hi Michele,
I'm happy that you got it to run the way you want.
I guess services such as the HDFS NameNode and YARNs ResourceManager are
running on the master.
I don't know what you are doing on the cluster, but I suspect it is for
experimentation only. As long as you are not maintaining a huge
Hi Michele,
the 10506 MB refer to the size of Flink's managed memory whereas the 20992
MB refer to the total amount of TM memory. At start-up, the TM allocates a
fraction of the JVM memory as byte arrays and manages this portion by
itself. The remaining memory is used as regular JVM heap for TM
Hi Fabian, thanks for your reply
so you flink is using about 50% of memory for itself right?
anyway now I am running an EMR with 1 master and 5 core all of them are
m3.2xlarge with 8 cores and 30GB of memory
I would like to run flink on yarn with 40 slots on 5 tm with the maximum
available
Hi Robert,
thanks for answering, today I have been able to try again: no in an EMR
configuration with 1 master and 5 core I have 5 active node in the resource
manager…sounds strange to me: ganglia shows 6 nodes and 1 is always offload
the total amount of memory is 112.5GB that is actually 22.5
Hi Michele,
configuring a YARN cluster to allocate all available resources as good as
possible is sometimes tricky, that is true.
We are aware of these problems and there are actually the following two

Hi everybody, i need a help on how to configure a yarn cluster
I tried a lot of conf but none of them was correct
We have a cluster on amazon emr let's say 1manager+5worker all of them are
m3.2xlarge then 8 core each and 30 GB of RAM each
What is a good configuration for such cluster?
I would
Hi Paul,
when you run your Flink cluster with YARN then we cannot give the full
amount of the allocated container memory to Flink. The reason is that YARN
itself needs some of the memory as well. Since YARN is quite strict with
containers which exceed their memory limit (the container is
11 matches
