General comment: I have concerns about recursive listing. This could be > abused by the applications, creating a lot of requests into HDFS. > 2. Any deletion of files/directories while reursing through directories > results in RuntimeException and application has a partial result. Should we > ignore if a directory was in stack and was not found later when iterating > through it? > 3. FileSystem.java > * listFile() - method javadoc could be better organized - first > write about if path is directory and two cases recursive=true and false. Then > if path is file and two cases recursive=true or false. > * listFile() - document throwing RuntimeException, > UnsupportedOperationException and the possible cause. IOException is no > longer thrown. > 4. TestListFiles.java > * testDirectory() - comments test empty directory and test > directory with 1 file should be moved up to relevant sections of the test. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
