How large is your graph, and how much memory does your cluster have? We don't have a good way to determine the *optimal* number of partitions aside from trial and error, but to get the job to at least run to completion, it might help to use the MEMORY_AND_DISK storage level and a large number of

Hello, We get a graph with 100B edges of nearly 800GB in gz format. We have 80 machines, each one has 60GB memory. I have not ever seen the program run to completion. Alcaid 2014-11-02 14:06 GMT+08:00 Ankur Dave ankurd...@gmail.com: How large is your graph, and how much memory does your

How to correctly extimate the number of partition of a graph in GraphX

2014-11-01 Thread James
Hello, I am trying to run Connected Component algorithm on a very big graph. In practice I found that a small number of partition size would lead to OOM, while a large number would cause various time out exceptions. Thus I wonder how to estimate the number of partition of a graph in GraphX?
