Steve Loughran commented on SPARK-2356:
---------------------------------------
It's coming from {{ UserGroupInformation.setConfiguration(conf)}}; UGI is
using Hadoop's {{StringUtils}} to do something, which then init's a static
variable
{code}
public static final Pattern ENV_VAR_PATTERN = Shell.WINDOWS ?
WIN_ENV_VAR_PATTERN : SHELL_ENV_VAR_PATTERN;
{code}
And Hadoop utils shell, does some stuff in its constructor, which depends on
winutils.exe being on the path.
convoluted, but there you go. HADOOP-11293 proposes factoring out the
{{Shell.Windows}} code into something standalone...if that can be pushed into
Hadoop 2.8 then this problem will go away from then on

> 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

> 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)
