--------------------------------------
Summary: FTPInputStream should close wrapped stream
Key: HADOOP-11136
URL: https://issues.apache.org/jira/browse/HADOOP-11136
Project: Hadoop Common
Issue Type: Improvement
Components: fs
Reporter: Dzianis Sokal
This is reproducible in PASSIVE FTP mode, which is not supported by
now(HADOOP-11135). However if we hack FTPFileSystem to enter into local passive
mode, it will hang on client.completePendingCommand() in FTPInputStream line
114:
{code}
...
public synchronized void close() throws IOException {
...
boolean cmdCompleted = client.completePendingCommand();
...
{code}
Going to completePendingCommand() docs I see that the stream should be closed
before calling it. So seems like stream should be closed
{code}
wrappedStream.close();
{code}
right before
{code}
boolean cmdCompleted = client.completePendingCommand();
{code}
