[email protected] From: Raajay Date: 2015-09-02 05:12 To: user Subject: DAG serialization Hi, Currently, I am running Hive on Tez. I wish to make some changes to the DAGs generated by Hive before running it on Tez; changes include altering parallelism and TaskLocationHints, etc.. Which DAG should I tap into from Hive, and write to disk, so that I can read later, alter it and then submit to Tez ? It does not seem like DAG.java in tez-api can be serialized. Raajay
