>                 Key: SPARK-24448
>                 URL: https://issues.apache.org/jira/browse/SPARK-24448
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core
>    Affects Versions: 2.2.1
>            Reporter: Pritpal Singh
>            Priority: Major

> I want to upload a file on all worker nodes in a standalone cluster and retrieve the location of file. Here is my code
>  
> val tempKeyStoreLoc = System.getProperty("java.io.tmpdir") + "/keystore.jks"
> val file = new File(tempKeyStoreLoc)
> sparkContext.addFile(file.getAbsolutePath)
> val keyLoc = SparkFiles.get("keystore.jks")
>  
> SparkFiles.get returns a random location where keystore.jks does not exist. I submit the job in cluster mode. In fact the location Spark.Files returns does not exist on any of the worker nodes (including the driver node). 
> I observed that Spark does load keystore.jks files on worker nodes at <SPARK_HOME>/work/<app_id>/<partition_id>/keystore.jks. The partition_id changes from one worker node to another.
> My requirement is to upload a file on all nodes of a cluster and retrieve its location. I'm expecting the location to be common across all worker nodes.
