CassandraDaemon
is an abstraction for a Cassandra daemon
service, which defines not only a way to activate and deactivate it, but also
hooks into its lifecycle methods (see AbstractCassandraDaemon.setup()
, AbstractCassandraDaemon.start()
,
AbstractCassandraDaemon.stop()
and AbstractCassandraDaemon.setup()
).BufferedRandomAccessFile
is like a
RandomAccessFile
, but it uses a private buffer so that most
operations do not require a disk access.CassandraDaemon

Cassandra daemon that runs on a single node.ColumnFamilyOutputFormat

OutputFormat that allows reduce tasks to store keys (and corresponding
values) as Cassandra rows (and respective columns) in a given
