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. -- This message is automatically generated by JIRA.
