Allen Wittenauer commented on HDFS-9525: ---------------------------------------- It'd be great if you read over the past comments instead of jumping to conclusions. Thanks. Also: bq. Snapping back the token files if that's the route you chose to follow, rather than a yack (yet another config key), why not add an option to fetchdt to add tokens to a file instead of overwriting the entire file?
