Reopening as there is a regression.
{code}
pi.py is under oozie.wf.application.path and workflow configuration is -
pyspark example
pi.py
${testConf}
pi.py#pi-renamed.py
{code}
With the change we added in this jira, it will call run the Spark job with
following params:
{code}
--master
yarn-cluster
--name
pyspark example
--conf
spark.driver.extraJavaOptions=-Dlog4j.configuration=spark-log4j.properties
--conf
spark.ui.view.acls=*
--queue
default
--conf
spark.executor.extraClassPath=$PWD/*
--conf
spark.driver.extraClassPath=$PWD/*
--conf
spark.yarn.security.tokens.hive.enabled=false
--conf
spark.yarn.security.tokens.hbase.enabled=false
--conf
spark.executor.extraJavaOptions=-Dlog4j.configuration=spark-log4j.properties
--properties-file

--verbose
hdfs://localhost/user/saley/examples/apps/spark-yarn-cluster/pi.py#pi-renamed.py

The job fails saying -
{code}
2017-02-07 21:59:24,847 [Driver] ERROR
org.apache.spark.deploy.yarn.ApplicationMaster - User application exited with
status 2
2017-02-07 21:59:24,849 [Driver] INFO
org.apache.spark.deploy.yarn.ApplicationMaster - Final app status: FAILED,
exitCode: 2, (reason: User application exited with status 2)
python: can't open file 'pi.py#pi-renamed.py': [Errno 2] No such file or
directory
{code}
Spark does not understand the {{#}} sign.
Therefore, we need to pass in the direct path for the file.
But at the same time, we also need to make sure that application jar won't get
distributed twice.
Solution - Mention the direct path for the application jar/py file if there is
a {{#}} sign (fragment) in the path. We can do so, because file is already
available in the launcher's local directory i.e. current directory. Also, at
the same time remove the application jar from *--files* option.

we need extra checks for PySpark dependencies otherwise those will get
distributed multiple times. The amend patch will also distribute the files
mentioned in and having {{#}}.
