Subject [jira] [Updated] (HBASE-13027) mapreduce.TableInputFormatBase should create its own Connection if needed
Date Sat, 14 Feb 2015 00:52:11 GMT

     [ https://issues.apache.org/jira/browse/HBASE-13027?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Busbey updated HBASE-13027:
--------------------------------
      Resolution: Fixed
    Release Note: The bindings for reading data from HBase using both the Hadoop MapReduce
mapred and mapreduce libraries now are initialized the same way. Subclasses wishing to build
on TableInputFormatBase that use the new initialize method will have access to job configuration
information.
          Status: Resolved  (was: Patch Available)

Pushed to 1.0.0+. Broke the 0.98 part into HBASE-13045 since having this ticket in the release
notes for the 0.98 line would be confusing.

> 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.
