Hi Suman, I'll assume that you are using spark submit to run your application. You can pass the --num-executors flag to ask for more containers. If you want to allocate more memory for each executor, you may also pass in the --executor-memory flag (this accepts a string in the format 1g, 512m etc.

How to increase parallelism in Yarn

2014-12-18 Thread Suman Somasundar
Hi, I am using Spark 1.1.1 on Yarn. When I try to run K-Means, I see from the Yarn dashboard that only 3 containers are being used. How do I increase the number of containers used? P.S: When I run K-Means on Mahout with the same settings, I see that there are 25-30 containers being used.
