--------------------------------------
Summary: Provide Merge API for MapFile to merge multiple similar
MapFiles to one MapFile
Key: HADOOP-11569
URL: https://issues.apache.org/jira/browse/HADOOP-11569
Project: Hadoop Common
Issue Type: Improvement
Reporter: Vinayakumar B
Assignee: Vinayakumar B
If there are multiple similar MapFiles of the same keyClass and value classes,
then these can be merged together to One MapFile to allow search easier.
Provide an API similar to {{SequenceFile#merge()}}.
Merging will be easy with the fact that MapFiles are already sorted.
