[jira] [Created] (HADOOP-18238) Hadoop 3.3.1 SFTPFileSystem.close() method have problem

yi liu created HADOOP-18238:
-------------------------------

             Summary: Hadoop 3.3.1 SFTPFileSystem.close() method have problem
                 Key: HADOOP-18238
                 URL: https://issues.apache.org/jira/browse/HADOOP-18238
             Project: Hadoop Common
          Issue Type: Bug
          Components: common
    Affects Versions: 3.3.1
            Reporter: yi liu


@Override
public void close() throws IOException {
if (closed.getAndSet(true)) {
return;
}
try {
super.close();
} finally {
if (connectionPool != null) {
connectionPool.shutdown();
}
}
}

 

if  you  exe this method ,the  fs can not exec deleteOnExsist method，because the fs is closed.

如果手动调用，sftp fs执行close方法关闭连接池，让jvm能正常退出，deleteOnExsist 将因为fs已关闭无法执行成功。如果不关闭，则连接池不会释放，jvm不能退出。

https://issues.apache.org/jira/browse/HADOOP-17528，这是3.2.0 sftpfilesystem的问题
