So far, we have used Shark to do some ETL work, which is not bad but is not prefect either. We ended writing UDF and UDGF, UDAF that can be avoided if we could use Pig. Do you have any suggestions with the ETL solution in Spark stack? And did any one have a working work flow management solution with Spark? Many thanks. Cao
