Rémy SAISSY created MAPREDUCE-5264:
--------------------------------------
Summary: FileAlreadyExistsException is assumed to be thrown by
FileSystem#mkdirs or FileContext#mkdir in the codebase
Key: MAPREDUCE-5264
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5264
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 3.0.0, 2.0.5-beta
Reporter: Rémy SAISSY
According to https://issues.apache.org/jira/browse/HADOOP-9438,
FileSystem#mkdirs and FileContext#mkdir do not throw FileAlreadyExistsException
if the directory already exist.
Some places in the mapreduce codebase assumes FileSystem#mkdirs or
FileContext#mkdir throw FileAlreadyExistsException.
At least the following files are concerned:
- YarnChild.java
- JobHistoryEverntHandler.java
- HistoryFileManager.java
It would be good to re-review and patch this if needed.
