The Session session = createSSHSession();
ChannelExec channelExec = null;
channelExec = (ChannelExec)session.openChannel("exec");
channelExec.setCommand("hdfs dfs -mkdir -p hdfs://user/19491/testfolder");
channelExec.connect();
BufferedReader br=new BufferedReader(new InputStreamReader(channelExec.getInputStream()));
String text;
while((text=br.readLine())!=null) {
System.out.println("Text is:"+text);
}
int exitStatus = channelExec.getExitStatus();
System.out.println("Exit status:"+exitStatus);
