ArchitectureGossip - Cassandra Wiki
Gossiper The gossiper is responsible for making sure every node in the system eventually knows important information about every other node's state, including those that are unreachable or not yet in the cluster when any given state change occurs. API Information to gossip is wrapped in an ApplicationState object, which is essentially a key/value pair. (See "Data Structures" below for more detail.

ArchitectureInternals - Cassandra Wiki
General Configuration file is parsed by DatabaseDescriptor (which also has all the default values, if any) Thrift generates an API interface in Cassandra.java; the implementation is CassandraServer, and CassandraDaemon ties it together (mostly: handling commitlog replay, and setting up the Thrift plumbing) CassandraServer turns thrift requests into the internal equivalents, then StorageProxy does
Hbase/ThriftApi - Hadoop Wiki
Thrift API This page discusses the Thrift client API for Hbase. Thrift is both cross-platform and more lightweight than REST for many operations. The latest version of the Hbase Thrift API is described by Hbase.thrift. Using the API Generating a Thrift client package Once Thrift is installed, use: thrift --gen [lang] [hbase-root]/src/main/resources/org/apache/hadoop/hbase/thrift/Hbase.thriftlang s
