Downloading Cassandra in Ubuntu 16.04


Installation from Debian packages

For the <release series> specify the major version number, without dot, and with an appended x.
The latest <release series> is 311x.
For older releases, the <release series> can be one of 30x, 22x, or 21x.

Add the Apache repository of Cassandra to /etc/apt/sources.list.d/cassandra.sources.list, for example for the latest 3.11 version:

echo "deb http://www.apache.org/dist/cassandra/debian 311x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
Add the Apache Cassandra repository keys:
curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -
Update the repositories:
sudo apt-get update

If you encounter this error:
GPG error: http://www.apache.org 311x InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A278B781FE4B2BDA
Then add the public key A278B781FE4B2BDA as follows:
sudo apt-key adv --keyserver pool.sks-keyservers.net --recv-key A278B781FE4B2BDA
and repeat
sudo apt-get update
. The actual key may be different, you get it from the error message itself. For a full list of Apache contributors public keys, you can refer to https://www.apache.org/dist/cassandra/KEYS.
  • Install Cassandra:
sudo apt-get install cassandra
  • You can start Cassandra with sudo service cassandra start and stop it with sudo service cassandra stop. However, normally the service will start automatically. For this reason be sure to stop it if you need to make any configuration changes.
  • Verify that Cassandra is running by invoking nodetool status from the command line.
  • The default location of configuration files is /etc/cassandra.
  • The default location of log and data directories is /var/log/cassandra/ and /var/lib/cassandra.
  • Start-up options (heap size, etc) can be configured in /etc/default/cassandra.

Normalization in DBMS: 1NF, 2NF, 3NF and BCNF in Database

Normalization is a process of organizing the data in database to avoid data redundancy, insertion anomaly, update anomaly & deletion anomaly. Let’s discuss about anomalies first then we will discuss normal forms with examples. Anomalies in DBMS There are three types of anomalies that occur when the database is not normalized. These are – Insertion, update and deletion anomaly. Let’s take an example to understand this. Example : Suppose a manufacturing company stores the employee details in a table named employee that has four attributes: emp_id for storing employee’s id, emp_name for storing employee’s name, emp_address for storing employee’s address and emp_dept for storing the department details in which the employee works. At some point of time the table looks like this: emp_id emp_name emp_address emp_dept 101 Rick Delhi D001 101 Rick Delhi D002 123 Maggie Agra D890 166 Glenn Chennai D900 166 Glenn Chennai D004 The above table ...
