[jira] [Created] (ACCUMULO-712) InputFormat that supports more than
one tablet per input split if on the same tablet server
Jim Donofrio created ACCUMULO-712:
-------------------------------------
Summary: InputFormat that supports more than one tablet per input split if on the same tablet server
Key: ACCUMULO-712
URL: https://issues.apache.org/jira/browse/ACCUMULO-712
Project: Accumulo
Issue Type: New Feature
Components: client
Reporter: Jim Donofrio
Assignee: Billie Rinaldi
Similar to CombineFileInputFormat for hdfs files, there should be an InputFormat that supports more than one tablet per input split if on the same tablet server. This should also work with ACCUMULO-391 to allow adding tablets from different compatible tables into a single input split. This allows mappers that finish very quickly to have more work to do. This could be a new InputFormat that extends AccumuloInputFormat or an option added to AccumuloInputFormat.
