Session taking all the available resources even with number of
cores specified
Hi everyone,
I am using livy 0.4 with Spark 2.1.0 standalone cluster.I can create sessions
and run jobs. but 1 session takes up all the available resources. I have tried
setting up executorCores, numExecutors as well as spark.total.executor.cores.
this command works fine when running a session from cmd line
./spark-2.1.0/bin/pyspark --master spark://master:7077 --executor-cores 2 --num-executors 1 --total-executor-cores 4
Not using Mixmax yet?

Is there any configuration I can do to limit the cores, so that I can run
multiple sessions on same cluster?

On create an issue popup I am unable to select Livy from project's dropdown,
there are other projects which I can select but not livy.

Hello everyone,

create a ticket around this?
Issue: Livy doesn't support "total-executor-cores" settings for spark standalone
cluster
This will enable livy to run multiple spark executors on standalone cluster.

Hey Junaid,
I did some digging in both Livy and Spark code and you are correct about the
issue being with total-executor-nodes. There is no such conf as
"spark.total.executor.nodes" in Spark as it only exists as a param to
spark-submit (which Spark then maps to the conf "spark.cores.max"). Also
currently Livy does not support that param when constructing it's
spark-submit, which would be useful and I would recommend opening a JIRA to
address it.
I can also point out a few issues with you POST for future reference while
I'm at it:
- The three "livy.spark.*" confs in your POST don't exist and would not be
used, also the value of "executorCores" is mapped to the conf
"spark.executor.cores" making it redundant
- Similarly "numExecutors" and "driverCores" map to
"spark.executor.instances" and "spark.driver.cores" respectively, which I
believe you tried setting with "livy.spark.*" formatted confs
So in summary you should open up a JIRA for Livy to support the
"total-executor-nodes" param for spark-submit and for now you can see if
setting "spark.cores.max" in the conf works as a work-around (though I'm not
hopeful)

Subject: Session taking all the available resources even with number of
cores specified
Hi everyone,
I am using livy 0.4 with Spark 2.1.0 standalone cluster.
I can create sessions and run jobs. but 1 session takes up all the
available resources. I have tried setting up executorCores, numExecutors
as well as spark.total.executor.cores. this command works fine when
running a session from cmd line
./spark-2.1.0/bin/pyspark --master spark://master:7077 --executor-cores 2
--num-executors 1 --total-executor-cores 4
Not using Mixmax yet?

Is there any configuration I can do to limit the cores, so that I can run
multiple sessions on same cluster?

Hi Alex,It is working correctly when i create spark session using bin/pyspark.
I can create multiple sessions as well. command which enable this is
"--total-executor-cores 4". I think livy is not passing it to Spark?
We are using DCOS and livy doesn't work with spark mesos deployment, so had to
setup standalone spark cluster.

Hi Junaid,
From my experience this is an issue with the Spark stand-alone cluster, which is
why Livy is recommended to run with YARN instead, which should allocate
resources properly. @Jerry, you have seen more production uses of LIvy than me,
am I correct that Livy with a stand-alone Spark cluster can't handle multiple
sessions?
