--------------------------------------
Summary: Support PASSIVE mode in FTPFileSystem
Key: HADOOP-11135
URL: https://issues.apache.org/jira/browse/HADOOP-11135
Project: Hadoop Common
Issue Type: Improvement
Components: fs
Reporter: Dzianis Sokal
org.apache.hadoop.fs.ftp.FTPFileSystem initializes
org.apache.commons.net.ftp.FTPClient with default
ACTIVE_LOCAL_DATA_CONNECTION_MODE and there is no way to alter that. The
FTPFileSystem related code hangs when ACTIVE connection can't be established.
Hangs in FTPClient line 490:
{code}
org.apache.commons.net.ftp.FTPClient._openDataConnection_{
...
if (!FTPReply.isPositivePreliminary(sendCommand(command, arg)))
...
}
{code}
