Upgrading
|
||||
---------
|
||||
- Fat client support has been removed since we have push notifications to clients
|
||||
- cassandra-cli has been removed. Please use cqlsh instead.
|
||||
- YamlFileNetworkTopologySnitch has been removed; switch to
|
||||
GossipingPropertyFileSnitch instead.

The client_only example uses the fat client to insert data into and read
|
||||
data from Cassandra.
|
||||
|
||||
-- Warning --
|
||||
The method used in this example (the fat client) should generally
|
||||
not be used instead of the thrift interface because of possible
|
||||
instability of the internal Cassandra API.
|
||||
|
||||
-- Prerequisite --
|
||||
Build the Cassandra source in the current source tree. Also, if
|
||||
running the client_only code against a local Cassandra node, start
|
||||
the local node prior to running the client_only script. See the
|
||||
configuration below for more info.
|
||||
|
||||
-- Build --
|
||||
To build, run ant from the contrib/client_only directory. It will build
|
||||
the source, then jar up the compiled class, the conf/cassandra.yaml, and
|
||||
dependencies into build/client_only.jar.
|
||||
|
||||
-- Run --
|
||||
To run, from the contrib/client_only directory run:
|
||||
bin/client_only write
|
||||
or
|
||||
bin/client_only read
|
||||
|
||||
'write' will create keyspace Keyspace1 and column family Standard1. If
|
||||
it is already there, it will error out. It will then write a bunch of
|
||||
data to the cluster it connects to.
|
||||
|
||||
'read' will read the data that was written in the write step.
|
||||
|
||||
-- Configuration --
|
||||
The conf/cassandra.yaml is to start up the fat client. The fat client
|
||||
joins the gossip network but does not participate in storage. It
|
||||
needs to have the same configuration as the rest of the cluster except
|
||||
listen address and rpc address. If you are running your cluster just
|
||||
on your local machine, you'll need to use another address for this node.
|
||||
Therefore, your local full Cassandra node can be 127.0.0.1 and the fat
|
||||
client can be 127.0.0.2. Such aliasing is enabled by default on linux.
|
||||
On Mac OS X, use the following command to use the second IP address:
|
||||
sudo ifconfig lo0 alias 127.0.0.2 up
|
||||
|
||||
cassandra.yaml can be on the classpath as is done here, can be specified
|
||||
(by modifying the script) in a location within the classpath like this:
|
||||
java -Xmx1G -Dcassandra.config=/path/in/classpath/to/cassandra.yaml ...
|
||||
or can be retrieved from a location outside the classpath like this:
|
||||
... -Dcassandra.config=file:///path/to/cassandra.yaml ...
|
||||
or
|
||||
... -Dcassandra.config=http://awesomesauce.com/cassandra.yaml ...

# ByteOrderedPartitioner, OrderPreservingPartitioner (deprecated)}.
|

#
|

# - RandomPartitioner distributes rows across the cluster evenly by md5.

# If space gets above this value (it will round up to the next nearest

# you can increase this value for better flush performance.

# By default this will be set to the amount of data directories defined.

# may be limited depending on use of stack space).

# The default is sync because on Windows hsha is about 30% slower. On Linux,
