------------------------------------
Summary: HBase should provide an InputFormat supporting multiple
scans in mapreduce jobs over snapshots
Key: HBASE-13356
URL: https://issues.apache.org/jira/browse/HBASE-13356
Project: HBase
Issue Type: New Feature
Components: mapreduce
Reporter: Andrew Mains
Priority: Minor
Currently, HBase supports the pushing of multiple scans to mapreduce jobs over
live tables (via MultiTableInputFormat) but only supports a single scan for
mapreduce jobs over table snapshots. It would be handy to support multiple
scans over snapshots as well, probably through another input format
(MultiTableSnapshotInputFormat?). To mimic the functionality present in
MultiTableInputFormat, the new input format would likely have to take in the
names of all snapshots used in addition to the scans.
