> 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
> Labels: hive
> Fix For: 1.0.0, 2.0.0
>
>
> Folks extending the mapreduce.TableInputFormatBase class and relying on the
> 0.98 way of doing table initialization (as given in the example in the
> javadoc) will currently always get an error.
> 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.
