INSTALL CQLSH FOR CASSANDRA 2.1 MAC SOFTWARE

cqlsh 5.0.1 Cassandra 3.0.9 CQL spec 3.4.0 Native protocol v4 Use HELP for help. To start cqlsh on OS X or Linux, simply type cqlsh into your command line you should see something like this: $ cqlsh Connected to Test Cluster at 127.0.01:9042.

But here is a drawback the cqlsh not available along with cassandra software so you should download and configure it separately. The cqlsh is called as interactive command tool using this we can interact with Cassandra database. Cqlsh Connected to Test Cluster at 127.0.0.1:9042. Then changed java version to 1.8 and ran the cassandra f.

Thanks, I got the same issue with java 11. You can manually start compaction using the nodetool compact command.So after I did that, then I went to the terminal, and initiated cqlsh and everything worked as expected, I really hope this helps. Additional parameters allow STCS to be tuned to increase or decrease the number of compactions it performs and how tombstones are handled. A minor compaction does not involve all the tables in a keyspace. This strategy triggers a minor compaction when there are a number of similar sized SSTables on disk as configured by the table subproperty min_threshold.

Choose a node to be your seed one, and look in the configuration file for the lines that refer to each of these attributes, and modify them to your needs: The information you'll need to edit either can be the same for all nodes (cluster_name, seed_provider, rpc_address and endpoint_snitch) or different for each one (initial_token, listen_address, broadcast_address and broadcast_rpc_address). $python -c 'number_of_tokens=3 print 'Ĭonfiguration on nodes is done through customizing cassandra.yaml file: For a single data center with 3 nodes, using the default Murmur3Partitioner: single data center, single seed Cassandra cluster:Īt this point you will calculate token numbers for all cluster nodes. Log back in and and confirm that everything is set properly:īefore configuring each node, make sure Cassandra is not running:Īs an example, I'll use a 3 node. You should now reboot the node, so everything is updated: To setup Cassandra environment variables, add the following lines to /etc/profile.d/cassandra.sh using vi or cat:Įxport CASSANDRA_HOME=/opt/apache-cassandra-2.2.8 $sudo chown -R $USER:$GROUP /var/log/cassandra

$sudo chown -R $USER:$GROUP /var/lib/cassandra Next, make sure that the folders Cassandra accesses, such as the log folder, exists and that Cassandra has the right to write on it:

Installing the Oracle JAVA VM on single nodes is detailed in TEC1354854. 0- The Cassandra documentation highly recommends the Oracle Java VM 8.
