Amazon Elastic MapReduce now supports Hadoop 0.20, Hive 0.5, and Pig 0.6.

With this update, Amazon Elastic MapReduce users can enjoy multiple inputs class for reading multiple types of data, and multiple outputs class for writing multiple types of data. Previously, customers could only run one reducer and one mapper per job; now, ChainMapper and ChainReducer allows multiple M+RM within one Hadoop job.
