OutOfMemoryError when running sbt/sbt test
Hi spark. I've been trying to build spark, but I've been getting lots of oome exceptions. https://gist.github.com/jayunit100/d424b6b825ce8517d68c For the most part, they are of the form: java.lang.OutOfMemoryError: unable to create new native thread I've attempted to hard code the get_mem_opts function, which is in the sbt-launch-lib.bash file, to have various very high parameter sizes (i.e. -Xms5g) with high MaxPermSize, etc... and to no avail. Any thoughts on this would be appreciated. I know of others having the same problem as well. Thanks! -- jay vyas

What is your ulimit value? On Tue, Aug 26, 2014 at 5:49 PM, jay vyas jayunit100.apa...@gmail.com wrote: Hi spark.

Re: OutOfMemoryError when running sbt/sbt test
Thanks...! Some questions below.
1) you are suggesting that maybe this OOME is a symptom/red herring , and the
true cause of it is that a thread can't span because of ulimit... If so
possibly this could be flagged early on in the build. And -- where are so many
threads coming from that I need to up my limit? Is this a new feature added
to spark recently, and if so will it effect deployments scenarios as well?
And
2) possibly SBT_OPTS is where the memory settings should be ? If so, then why
do we have the get_mem_opts wrapper function coded to send memory manually as
Xmx/Xms options?
execRunner $java_cmd \
${SBT_OPTS:-$default_sbt_opts} \
$(get_mem_opts $sbt_mem) \
${java_opts} \
${java_args[@]} \
-jar $sbt_jar \
${sbt_commands[@]} \
${residual_args[@]}

For the most part, they are of the form:
java.lang.OutOfMemoryError: unable to create new native thread
I've attempted to hard code the get_mem_opts function, which is in the
sbt-launch-lib.bash file, to
have various very high parameter sizes (i.e. -Xms5g) with high
MaxPermSize, etc... and to no avail.

Re: OutOfMemoryError when running sbt/sbt test
Hi Jay, The recommended way to build spark from source is through the maven system. You would want to follow the steps in https://spark.apache.org/docs/latest/building-with-maven.html to set the MAVEN_OPTS to prevent OOM build errors.
