> sc.textFile(my_file).collect() raises socket.timeout on large files

>                 Key: SPARK-18649
>                 URL: https://issues.apache.org/jira/browse/SPARK-18649
>             Project: Spark
>          Issue Type: Bug
>          Components: PySpark
>         Environment: PySpark version 1.6.2
>            Reporter: Erik Cederstrand
>
> I'm trying to load a file into the driver with this code:
>     contents = sc.textFile('hdfs://path/to/big_file.csv').collect()
> Loading into the driver instead of creating a distributed RDD is intentional 
> in this case. The file is ca. 6GB, and I have adjusted driver memory 
> accordingly to fit the local data. After some time, my spark/submitted job 
> crashes with the stack trace below.
> I have traced this to pyspark/rdd.py where the _load_from_socket() method 
> creates a socket with a hard-coded timeout of 3 seconds (this code is also 
> present in HEAD although I'm on PySpark 1.6.2). Raising this hard-coded value 
> to e.g. 600 lets me read the entire file.
> Is there any reason that this value does not use e.g. the 
> 'spark.network.timeout' setting instead?
> Traceback (most recent call last):
