-------------------------------
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
