Subject [jira] [Created] (HBASE-7995) Export$Exporter could be replaced with IdentityTableMapper
Date Mon, 04 Mar 2013 21:37:12 GMT
Nick Dimiduk created HBASE-7995:
-----------------------------------

             Summary: Export$Exporter could be replaced with IdentityTableMapper
                 Key: HBASE-7995
                 URL: https://issues.apache.org/jira/browse/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}
