Subject [jira] [Commented] (SPARK-2356) Exception: Could not locate executable null\bin\winutils.exe in the Hadoop
Date Sun, 01 Feb 2015 15:45:35 GMT

    [ https://issues.apache.org/jira/browse/SPARK-2356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14300243#comment-14300243

DeepakVohra commented on SPARK-2356:
------------------------------------

Thanks Sean. 

HADOOP_CONF_DIR shouldn't be required to be set if Hadoop is not used. 

Hadoop doesn't even get installed on Windows.

> I'm trying to run some transformation on Spark, it works fine on cluster (YARN, linux
machines). However, when I'm trying to run it on local machine (Windows 7) under unit test,
I got errors (I don't use Hadoop, I'm read file from local filesystem):

> It's happened because Hadoop config is initialized each time when spark context is created
regardless is hadoop required or not.
> I propose to add some special flag to indicate if hadoop config is required (or start
this configuration manually)
