Spark SQL reduce number of java threads

2014-10-28 Thread Wanda Hawk
Hello I am trying to reduce the number of java threads (about 80 on my system) to as few as there can be. What settings can be done in spark-1.1.0/conf/spark-env.sh ? (or other places as well) I am also using hadoop for storing data on hdfs Thank you, Wanda

What is the motivation behind this ? You can start with master as local[NO_OF_THREADS]. Reducing the threads at all other places can have unexpected results. Take a look at this. http://spark.apache.org/docs/latest/configuration.html. Prashant Sharma On Tue, Oct 28, 2014 at 2:08 PM, Wanda
