    cassandra-env.sh file

    cassandra-env.sh bash script file can be used to pass additional options to the Java virtual machine (JVM), such as maximum and minimum heap size, rather than setting them in the environment. If the JVM settings are static and do not need to be computed from the node characteristics, the cassandra-jvm-options files should be used instead. For example, commonly computed values are the heap sizes, using the system values. JVM_OPTS="$JVM_OPTS -Dcassandra.load_ring_state=false" to the cassandra_env.sh file and run the command-line cassandra to start. The option is set from the cassandra-env.sh file, and is equivalent to starting Cassandra with the command-line option cassandra -Dcassandra.load_ring_state=false. -D option specifies the start-up parameters in both the command line and cassandra-env.sh file. The following options are available:

    cassandra.auto_bootstrap=false

    cassandra.yaml file on each node to revert to true, the default value.

    cassandra.available_processors=<number_of_processors>

    In a multi-instance deployment, multiple Cassandra instances will independently assume that all CPU processors are available to it. This setting allows you to specify a smaller set of processors.

    cassandra.boot_without_jna=true

    If JNA fails to initialize, Cassandra fails to boot. Use this command to boot Cassandra without JNA.

    cassandra.config=<directory>

    cassandra.yaml file. The default location depends on the type of installation.

    cassandra.ignore_dynamic_snitch_severity=true|false

    Setting this property to true causes the dynamic snitch to ignore the severity indicator from gossip when scoring nodes. Explore failure detection and recovery and dynamic snitching for more information. Default: false

    cassandra.initial_token=<token>

    Use when virtual nodes (vnodes) are not used. Sets the initial partitioner token for a node the first time the node is started. Note: Vnodes are highly recommended as they automatically select tokens. Default: disabled

    cassandra.join_ring=true|false

    nodetool join and a JMX call to join the ring afterwards. Default: true

    cassandra.load_ring_state=true|false

    Set to false to clear all gossip state for the node on restart. Default: true

    cassandra.metricsReporterConfigFile=<filename>

    Enable pluggable metrics reporter. Explore pluggable metrics reporting for more information.

    cassandra.partitioner=<partitioner>

    Set the partitioner. Default: org.apache.cassandra.dht.Murmur3Partitioner

    cassandra.prepared_statements_cache_size_in_bytes=<cache_size>

    Set the cache size for prepared statements.

    cassandra.replace_address=<listen_address of dead node>|<broadcast_address of dead node>

    listen_address or broadcast_address that the new node is assuming. The new node must not have any data in its data directory, the same state as before bootstrapping. Note: The broadcast_address defaults to the listen_address except when using the Ec2MultiRegionSnitch.

    cassandra.replayList=<table>

    Allow restoring specific tables from an archived commit log.

    cassandra.ring_delay_ms=<number_of_ms>

    Defines the amount of time a node waits to hear from other nodes before formally joining the ring. Default: 1000ms

    cassandra.native_transport_port=<port>

    Set the port on which the CQL native transport listens for clients. Default: 9042

    cassandra.rpc_port=<port>

    Set the port for the Thrift RPC service, which is used for client connections. Default: 9160

    cassandra.storage_port=<port>

    Set the port for inter-node communication. Default: 7000

    cassandra.ssl_storage_port=<port>

    Set the SSL port for encrypted communication. Default: 7001

    cassandra.start_native_transport=true|false

    start_native_transport in cassandra.yaml. Default: true

    cassandra.start_rpc=true|false

    Enable or disable the Thrift RPC server. Default: true

    cassandra.triggers_dir=<directory>

    Set the default location for the trigger JARs. Default: conf/triggers

    cassandra.write_survey=true

    For testing new compaction and compression strategies. It allows you to experiment with different strategies and benchmark write performance differences without affecting the production workload.

    consistent.rangemovement=true|false

    Set to true makes Cassandra perform bootstrap safely without violating consistency. False disables this.
