[jira] [Created] (HADOOP-18313) AliyunOSS: AliyunOSSBlockOutputStream should not mark the temporary file for deletion

wujinhu created HADOOP-18313:
--------------------------------

             Summary: AliyunOSS: AliyunOSSBlockOutputStream should not mark the temporary file for deletion
                 Key: HADOOP-18313
                 URL: https://issues.apache.org/jira/browse/HADOOP-18313
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/oss
    Affects Versions: 3.3.3, 3.2.3, 2.10.2
            Reporter: wujinhu
            Assignee: wujinhu


AliyunOSSBlockOutputStream buffers data in local directory before uploading to OSS. It uses LocalDirAllocator.createTmpFileForWrite which will create a temp file on this directory and invoke DeleteOnExitHook.add to add the path to a set and will be deleted on VM exit through a shutdown hook. However, the size of set will be growing if the VM does not exit.
