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 wrote: > Thanks a lot for your information. It really helps me. > > > On Tue, Apr 15, 2014 at 7:57 PM, C

Probably this JIRA issuesolves 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

StackOverflow Error when run ALS with 100 iterations

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 up
