-------------------------------------
I tested pig-test on trunk and found some failed test cases, I am fixing those
in this ticket as well.
> Remove depency of hadoop to internals (Cell/CellName)
> -----------------------------------------------------

> Key: CASSANDRA-8609
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8609
> Project: Cassandra
> Issue Type: Bug
> Reporter: Sylvain Lebresne
> Assignee: Alex Liu
> Fix For: 3.0

>
> For some reason most of the Hadoop code (ColumnFamilyRecordReader,
> CqlStorage, ...) uses the {{Cell}} and {{CellName}} classes. That dependency
> is entirely artificial: all this code is really client code that communicate
> with Cassandra over thrift/native protocol and there is thus no reason for it
> to use internal classes. And in fact, thoses classes are used in a very crude
> way, as a {{Pair<ByteBuffer, ByteBuffer>}} really.
> But this dependency is really painful when we make changes to the internals.
> Further, every time we do so, I believe we break some of those the APIs due
> to the change. This has been painful for CASSANDRA-5417 and this is now
> painful for CASSANDRA-8099. But while I somewhat hack over it in
> CASSANDRA-5417, this was a mistake and we should have removed the depency
> back then. So let do that now.
