[jira] [Commented] (SPARK-5164) YARN | Spark job submits from
windows machine to a linux YARN cluster fail
[ https://issues.apache.org/jira/browse/SPARK-5164?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14270533#comment-14270533 ]
Aniket Bhatnagar commented on SPARK-5164:
-----------------------------------------
First issue can be fixed by using Environment.<variable>.$$() instead of Environment.<variable>.$() in ClientBase. But unfortunately, $$() method seems to be only added in recent versions of hadoop making it not a viable option if we want to support many versions of Hadoop.
I am not sure if it is possible to detect remote OS using YARN API. I am thinking that perhaps we should introduce a new configuration - spark.yarn.remote.os that hints about the target YARN OS an can take values - Windows or Linux. We can then use this configuration in ClientBase and Path.SEPARATOR. I am happy to submit a pull request for this, once the recommendation is vetted by the community.

> Key: SPARK-5164
> URL: https://issues.apache.org/jira/browse/SPARK-5164
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 1.2.0
> Environment: Spark submit from Windows 7
> YARN cluster on CentOS 6.5
> Reporter: Aniket Bhatnagar
>
> While submitting spark jobs from a windows machine to a linux YARN cluster, the jobs fail because of the following reasons:
> 1. Commands and classpath contain environment variables (like JAVA_HOME, PWD, etc) but are added as per windows's syntax (%JAVA_HOME%, %PWD%, etc) instead of linux's syntax ($JAVA_HOME, $PWD, etc).
> 2. Paths in launch environment are delimited by semi-colon instead of colon. This is because of usage of Path.SEPARATOR in ClientBase and YarnSparkHadoopUtil.
