Just wanted to add a comment to the Jira ticket but I don't think I have permission to do so, so answering here instead. I am encountering the same issue with a stackOverflow Exception. I would like to point out that there is a localCheckpoint

Hi, would you please how to checkpoint the training set rdd since all things are done in ALS.train method. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/StackOverflow-Error-when-run-ALS-with-100-iterations-tp4296p22619.html Sent from the Apache Spark User

I'd also say that running for 100 iterations is a waste of resources, as ALS will typically converge pretty quickly, as in within 10-20 iterations. On Wed, Apr 16, 2014 at 3:54 AM, Xiaoli Li lixiaolima...@gmail.com wrote: Thanks a lot for your information. It really helps me. On Tue, Apr

StackOverflow Error when run ALS with 100 iterations

2014-04-15 Thread Xiaoli Li
Hi, I am testing ALS using 7 nodes. Each node has 4 cores and 8G memeory. ALS program cannot run even with a very small size of training data (about 91 lines) due to StackVverFlow error when I set the number of iterations to 100. I think the problem may be caused by updateFeatures method which

Probably this JIRA issuehttps://spark-project.atlassian.net/browse/SPARK-1006solves your problem. When running with large iteration number, the lineage DAG of ALS becomes very deep, both DAGScheduler and Java serializer may overflow because they are implemented in a recursive way. You may resort
