------------------------------------
Summary: Fix filename conflicts in actions
Key: OOZIE-2190
URL: https://issues.apache.org/jira/browse/OOZIE-2190
Project: Oozie
Issue Type: Bug
Components: action
Reporter: Robert Kanter
We've seen issues where if you have a hive-site.xml with the Hive action or a
sqoop-site.xml with the Sqoop action, it fails because of a name conflict (the
action wants to write a file with the same name). We should go through all of
the actions and look for any filenames that go into the working directory and
try to fix these name conflicts. Here are some ideas on how to fix this:
# Generate a subdir in the working directory named "oozie-<timestamp>" and put
all files generated by the action in there; it would be extremely unlikely for
the user to have a directory named that.
# Before creating any files in the action, we check if that file already exists
and if so, rename it
# Add "-<timestamp>" to the filenames generated by actions
I think option 1 is the easiest and best for maintainability. We can make some
helper method that all of the actions can use that returns the directory that's
created and just make sure to put any created files in there.
