Appending is an HDFS issue. I haven't followed it closely, but I know it was only added relatively recently (if at all) and I personally haven't used it. Generally, you can't append to files.
"Updating a file" in our workflows generally involves making a new file, then deleting and moving the new file to replace the old one. 2012/6/1 Michael G. <[email protected]> > Hi all > I'm new in pig and in hadoop . > Can you tell me how I can : > 1. append to existing file on HDFS with pig > 2. update file with pig, if it could be passible. > > 10x. > > -- > -- Michael G. -- >
