Chao Shi commented on CRUNCH-308:
---------------------------------
Great work, Josh!
I like the hack on PType. Just to make sure if I understand this correctly: no
serialization will happen in our code when using KeyValue/Mutation with the
output target directly (as this is handled by the MR framework). If we write
them to a SeqFile target, it will call the ptype serialization function, i.e.
HBaseTypes#MapOutFn. Am I right?
I think I will need to have closer look on this patch. :)
> Upgrade to Hadoop 2.2.0 and HBase 0.96

>
> As discussed on dev@crunch, we should update Crunch to run against the new
> mainline releases of Hadoop (2.2.0) and HBase (0.96).
> There isn't a good way to maintain a shim between HBase 0.94 and HBase 0.96
> due to a number of API changes, so this change means that support for HBase
> 0.94 will remain in the 0.8.x sequence of Crunch releases, and 0.96 will be
> the supported version from 0.9.0 onwards.
