-----------------------------------------
This is why the patch broke the build :
{noformat}
- return (Mapper.Context)
MAP_CONTEXT_CONSTRUCTOR.newInstance((Mapper<K1,V1,K2,V2>)
MAP_CONSTRUCTOR.newInstance(), basis);
+ @SuppressWarnings("unchecked")
+ Mapper<K1,V1,K2,V2>.Context newInstance =
(Mapper<K1,V1,K2,V2>.Context)
MAP_CONTEXT_CONSTRUCTOR.newInstance(MAP_CONSTRUCTOR.newInstance(), basis);
+ return newInstance;
} else {
- return (Mapper.Context) MAP_CONTEXT_CONSTRUCTOR.newInstance(m,
tac.getConfiguration(), tac.getTaskAttemptID(), reader, writer, committer,
reporter,
- split);
+ @SuppressWarnings("unchecked")
+ Mapper<K1,V1,K2,V2>.Context newInstance =
(Mapper<K1,V1,K2,V2>.Context) MAP_CONTEXT_CONSTRUCTOR.newInstance(m,
tac.getConfiguration(),
+ tac.getTaskAttemptID(), reader, writer, committer, reporter,
split);
+ return newInstance;

If you take a look at the svn log for ContextFactory, you'll see I made the
same mistake when I first checked it in and fixed it in revision 1229638:
http://svn.apache.org/viewvc/accumulo/trunk/core/src/main/java/org/apache/accumulo/core/util/ContextFactory.java?view=log
> Allow the properties for AccumuloFileOutputFormat to be set in a mapreduce job

> Project: Accumulo
> Issue Type: Improvement
> Components: client
> Affects Versions: 1.4.1, 1.3.6, 1.4.0, 1.3.5
> Reporter: Chris Waring
> Assignee: Christopher Tubbs
> Priority: Minor
> Labels: AccumuloFileOutputFormat,, mapreduce
> Fix For: 1.5.0

> Attachments: ACCUMULO-467-1.patch
>
>
> Currently there is no way to set any of the configuration options for
> AccumuloFileOutputFormat in a mapreduce job. Specifically the compression
> code, file block compression size, and index block compression size to name a
> few. Since AccumuloFileOutputFormat calls
> FileOperations.getInstance.openWriter() which takes both a Configuration and
> AccumuloConfiguration one could inside the openWriter function check to see
> if the parameters are specified in the Configuration object and if not take
> the default parameters from the AccumuloConfiguration object.
