Andrew Mains updated HBASE-13356: --------------------------------- Assignee: Andrew Mains Status: Patch Available (was: Open) Attached patch contains mapred and mapreduce implementations of MultiTableSnapshotInputFormat, with tests. > 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 > Assignee: Andrew Mains > Priority: Minor > Attachments: HBASE-13356.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
