Aleksey Yeschenko commented on CASSANDRA-8609: ---------------------------------------------- With Thrift-based Hadoop code going away in 3.0/CASSANDRA-9353 it's important that the 2.2 versions of it can work without any internal dependencies (so that you can use the 2.2 versions with 3.0, if you need to). > 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: Philip Thompson > Fix For: 2.2 rc1 > > Attachments: CASSANDRA-8609-3.0-branch.txt > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
