> Spark Job fails if the fs.defaultFs and url where application jar resides are different
and having same scheme,
> spark-submit  --conf spark.master=yarn-cluster wasb://XXX/tmp/test.py
> core-site.xml fs.defaultFS is set to wasb:///YYY. Hadoop list works (hadoop fs -ls) works
for both the url XXX and YYY.
> {code}
> Exception in thread "main" java.lang.IllegalArgumentException: Wrong FS: wasb://XXX/tmp/test.py,

> The code Client.copyFileToRemote tries to resolve the path of application jar (XXX) from
the FileSystem object created using fs.defaultFS url (YYY) instead of the actual url of application
jar.
> val destFs = destDir.getFileSystem(hadoopConf)
> val srcFs = srcPath.getFileSystem(hadoopConf)
> getFileSystem will create the filesystem based on the url of the path and so this is
fine. But the below lines of code tries to get the srcPath (XXX url) from the destFs (YYY
url) and so it fails.
> var destPath = srcPath
> val qualifiedDestPath = destFs.makeQualified(destPath)
