----------------------------------------
Hi Renato,
I think you have a valid point, and may be its a better strategy in a long run.
But, from my point of view of a casual user, Gora is fine as long as its
current version is able to run on the most popular version of Hadoop/HBase,
meaning the current versions that ship with either CDH or HDP. In my
experience, only big companies are able to maintain their own in-house Hadoop
stack based on Apache, all the rest run on the commercial distributions (or
their community editions). So the new Nutch/Gora users will likely to have
experience with these distributions and would prefer if Nutch/Gora can run on
them out of the box. Given the limited dev resources, it's probably the best
strategy to aim at the low hanging fruit first.
I think it's ok to have only two profiles, one for Hadoop1/HBase0.94 and the
other for Hadoop2/Hbase 0.96/0.98. Eventually, Gora can drop Hadoop1 profile so
it's only need for the transitional period.
I have opened JIRA to support the next version of HBase here (with a patch):
https://issues.apache.org/jira/browse/GORA-343
I will likely have some time this weekend, and I can try to prepare the
hadoop1/hadoop2 profile patch, unless there are objections.

> TaskAttemptContext and JobContext which were a class in previous hadoop
> versions are now interfaces.
> Compiling gora with new hadoop version 2 fails.
> BinaryDecoder and BinaryEncoder in Avro 1.5.4 are also now interfaces which
> were previously class.
