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()
).BATCH UPDATE

is like a
RandomAccessFile
, but it uses a private buffer so that most
operations do not require a disk access.CassandraDaemon
interface captures the lifecycle of a
Cassandra daemon that runs on a single node.ColumnFamilyOutputFormat
acts as a Hadoop-specific
OutputFormat that allows reduce tasks to store keys (and corresponding
values) as Cassandra rows (and respective columns) in a given

only goes as far as extracting the keyword arguments
from these statements, so this method is responsible for processing and
validating, and must be called prior to access.
