Overview/Description
Apache HBase is written in Java and therefore there are multiple ways to access HBase using various clients. One client is the HBase shell, which is a command-line utility that provides client and administrative operations. HBase also provides access through the use of a Java client API to provide basic and advanced client and administrative operations. This course will discuss and demonstrate the various tasks you can accomplish using the shell and Java client API, including creating tables, reading and writing data, and updating and deleting.

Target Audience
Administrators and developers who need experience using HBase

Apache HBase Fundamentals: Access Data through the Shell and Client API

start the course

create a table using the shell in HBase

enable, disable, and drop a table using the shell in HBase

alter an HBase table's properties

add data to an HBase table using the put shell command

use the scan and get shell commands to retrieve data from an HBase table

delete data from an HBase table

increment the counter using the incr shell command and get the counter value using get_counter

establish a connection to HBase using a Java API with the HConnection, HTable, and HTablePool

create tables using the client Java API

create a Put class instance with a rowkey to store data in an HBase table

add data to an HBase table using the add() method in the Put instance

specify a timestamp within a Put constructor to specify different versions

use the get() and has() methods to check the existence of a column in an HBase table

use the Get class to read data from an HBase table

use the addFamily() and addColumn () methods of the Get class

use the setTimeRange(), setTimeStamp(), and setMaxVersions() methods of the Get class to retrieve versions of columns

use the getValue() and getColumnLast() to retrieve specific values from cells in an HBase table

use List with the Get class to return a list of values in a batch

use Scan() to read an entire HBase table

use Scan() to read a table starting at a specific row or scan a range of rows from an HBase table

use different methods to further narrow search results from a Scan constructor

use the getScanner() methods to get the instance of a scan and browse the results

use the ResultScanner class to retrieve the rows from the scanner

update data in an HBase table using the Put instance

delete data from an HBase table

create an HBase table and insert, update, delete, and retrieve data using the Java Client API
