------------------------------

Thanks for doing this Nick.
I think ITM came in w/ the first MR hookups done by a kind gentleman over at
IBM.
I might have done Export. Should have been smarter and used ITM.
I can go back through svn/git history to jog by my old brain if you need more
than the above.
> Export$Exporter could be replaced with IdentityTableMapper

> Key: HBASE-7995

> Project: HBase
> Issue Type: Improvement
> Components: mapreduce
> Reporter: Nick Dimiduk
> Priority: Minor
>
> The Mapper implementation in Export looks identical to IdentityTableMapper,
> except for the (poor) exception handling. I'd like to consolidate on
> IdentityTableMapper, but I'm looking for some historical perspective before
> doing so (cc [~stack])
> Export$Exporter's map method:
> {code}
> public void map(ImmutableBytesWritable row, Result value, Context context)
> throws IOException {
> try {
> context.write(row, value);
> } catch (InterruptedException e) {
> e.printStackTrace();
> }
> }
> {code}
> IdentityTableMapper's map method:
> {code}
> public void map(ImmutableBytesWritable key, Result value, Context context)
> throws IOException, InterruptedException {
> context.write(key, value);
> }
> {code}
