Hi, Does anyone have experience running MultiStorage-like UDF on Elastic MapReduce? Basically we are trying to store output into multiple directories based on certain field values. We have some success writing UDF that extends MultiStorage in piggybank to write to HDFS, but we couldn't get the same UDF to write to S3. We also couldn't find MultiStorage in Amazon's version of piggybank. Any suggestions on how we can achieve that on Elastic MapReduce writing to S3? Thanks in advance!
Thanks, Jialong
