             Summary: Deprecated mapreduce.TableInputFormatBase initialization always fails
                 Key: HBASE-13027
                 URL: https://issues.apache.org/jira/browse/HBASE-13027
             Project: HBase
          Issue Type: Bug
          Components: mapreduce
    Affects Versions: 1.0.0
            Reporter: Sean Busbey
            Assignee: Sean Busbey
            Priority: Blocker
             Fix For: 1.0.0, 2.0.0

When taking in a HTable, the current implementation retrieves a Connection instance from the
table and then an Admin instance from said Connection. The getAdmin call validates that it
only is called on unmanaged connections, but when folks construct an HTable instance according
to the examples, it ends up backed by a managed connection.
