Andrew Or updated SPARK-1900:
-----------------------------
Description:
If I run the following on a YARN cluster
```
bin/spark-submit sheep.py --master yarn-client
```
it fails because of a mismatch in paths: `spark-submit` thinks that `sheep.py`
resides on HDFS, and balks when it can't find the file there. A natural
workaround is to add the `file:` prefix to the file:
```
bin/spark-submit file:/path/to/sheep.py --master yarn-client
```
However, this also fails. This time it is because python does not understand
URI schemes.
This PR fixes this by automatically resolving all paths passed as command line
argument to `spark-submit` properly. This has the added benefit of keeping file
and jar paths consistent across different cluster modes.
was:
This fails currently because of a mismatch in paths.
On a YARN cluster, spark-submit automatically assumes the file is on HDFS, even
if it is a relative path that refers to a local file. A natural workaround for
this is to explicitly specify the "file:" prefix. However, this prefix is not
understood by python, which fails with the following:
{code}
python: can't open file 'file:path/to/my/file.py': [Errno 2] No such file or
directory
{code}
