> Bulk Import fails with java.io.IOException: Type mismatch in value from map

> Key: HBASE-25839
> URL: https://issues.apache.org/jira/browse/HBASE-25839
> Project: HBase
> Issue Type: Bug
> Components: mapreduce
> Affects Versions: 2.2.5
> Reporter: ZFabrik
> Assignee: Y. SREENIVASULU REDDY
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.7.0, 3.0.0-beta-2, 2.6.3, 2.5.12

> The Problem is that in
> {{org.apache.hadoop.hbase.mapreduce.Import.CellSortImporter#map}} the
> {{Cell}} coming from {{value.rawCells()}} (which is of type
> {{org.apache.hadoop.hbase.IndividualBytesFieldCell}}) is directly written to
> the context without wrapping it into {{MapReduceExtendedCell}} (like it
> happens at {{CellImporter#map}}).
> IMHO [line
> 423|https://github.com/apache/hbase/blob/f76a601273e834267b55c0cda12474590283fd4c/hbase-mapreduce/src/main/java/org/apache/hadoop/hbase/mapreduce/Import.java#L423]
> must look like this:
> {code:java}
> context.write(new CellWritableComparable(ret), new
> MapReduceExtendedCell(ret));
> {code}
> Furthermore it seems to me that this is also wrong in all subsequent versions
>
