> LongWritable.compareTo needs shimming
> -------------------------------------

> Key: HIVE-6105
> URL: https://issues.apache.org/jira/browse/HIVE-6105
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.12.0

> Compiled hive against hadoop-2. Running tests on hadoop 1 gives:
> Caused by: java.lang.NoSuchMethodError:
> org.apache.hadoop.io.LongWritable.compareTo(Lorg/apache/hadoop/io/LongWritable;)I

> I think the problem is that the compareTo function has changed from using
> Object to using LongWritable as an argument. Seems this needs a shim.
> However, we should also make sure that this shim doesn't hit performance too
> hard.
