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
