[jira] [Commented] (SPARK-12261) pyspark crash for large dataset
[ https://issues.apache.org/jira/browse/SPARK-12261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15115433#comment-15115433 ]
Christopher Bourez commented on SPARK-12261:
--------------------------------------------
I think the issue is not resolved
I installed spark 1.6 on many different computers.
On Windows, PySpark textfile method, followed by take(1), does not work on a file of 13M.
If I set numpartitions to 2000 or take a smaller file, the method works well.
The Pyspark is set with all RAM memory of the computer thanks to the command --conf spark.driver.memory=5g in local mode.
On Mac OS, I'm able to launch the exact same program with Pyspark with 16G RAM for a file of much bigger in comparison, of 5G. Memory is correctly allocated, removed etc
On Ubuntu, no trouble, I can also launch a cluster http://christopher5106.github.io/big/data/2016/01/19/computation-power-as-you-need-with-EMR-auto-termination-cluster-example-random-forest-python.html
The error message on Windows is : java.net.SocketException: Connection reset by peer: socket write error
What could be the reason to have the windows spark textfile method fail ?

> I tried to import a local text(over 100mb) file via textFile in pyspark, when i ran data.take(), it failed and gave error messages including:

> Then i ran the same code for a small text file, this time .take() worked fine.
> How can i solve this problem?
