--------------------------------
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.
