Daniel Carl Jones updated HADOOP-18238:
---------------------------------------
Description:
{code:java}
@Override
public void close() throws IOException {
if (closed.getAndSet(true)) {
return;
}
try {
super.close();
} finally {
if (connectionPool != null) {
connectionPool.shutdown();
}
}
}
{code}
if you execute this method, the fs can not execute the deleteOnExit 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
Translated:
{quote}If it is called manually, sftp fs executes the close method to close the
connection pool, so that the jvm can exit normally, deleteOnExist will fail to
execute successfully because fs is closed. If it is not closed, the connection
pool will not be released and the jvm cannot exit.

if (connectionPool != null) {

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