------------------------------------
Summary: It should be possible to chain-load multiple MapFiles on
the fly and read the records in an ascending order
Key: MAPREDUCE-6218
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6218
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Jens Rabe
Priority: Minor
In a scenario where there are many MapFiles which all share the same key/value
types, e.g., when dealing with measured data from sensors, it should be
possible to chain-load multiple MapFiles. That means, there should be a reader
which can be supplied with one or more directories containing MapFiles, and it
should be possible to read the records of all files in order.
