In this HBase training course you will learn the basics of HBase. You will learn the installation, architecture and data modeling in HBase. Finally you wil learn to use shell and Java client API in HBase, the implementation of filters and using MapReduce.
Among subjects that covered are HFile, Redion components, MAPReduce, shell command, JAVA API, addFamily, setTimeRange, Merge utility and far more.
Result
After completing this course you will be familiar with the basics of Apache HBase.
Prerequisites

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
Apache HBase Fundamentals: Advanced API, Administration, and MapReduce
start the course
use utility filters that extend the FilterBase class to filter scan results
use comparison filters to limit the scan results using comparison operators and comparator instance
use custom filters to extend or change the behavior of an existing filter to achieve a more fine-grained control over the scan results
use the HBaseAdmin API to check the status of the master server, connection instance, and the configuration used by the instance
view a list of all the user space tables in HBase and the instance for the table
disable and delete tables from HBase
complete a major compaction using the HBase shell
merge regions in the same table using the Merge utility
stop and decommission a RegionServer
perform a rolling restart on the entire cluster
add a new node to HBase
view metrics to monitor HBase
take a snapshot
use a snapshot to clone a table and move it to another cluster
export and restore a snapshot to another cluster
perform a full shutdown backup of HBase
perform a backup of HBase on a live cluster
restore HBase
use the TableOutPutFormat class to set up a table as an output to the MapReduce process using HBase as the data sink
set up a table as an input to a MapReduce process using HBase as the data source
use MapReduce to bulk load data directly into HBase file system by bypassing the HBase API
use the getSplits method of the TableInputFormatBase class to create custom splitters when using an HBase table as a data source
access other HBase tables from within a MapReduce job by creating a Table instance in the setup method of Mapper
perform HBase cluster and node maintenance
Course options
We offer several optional training products to enhance your learning experience. If you are planning to use our training course in preperation for an official exam then whe highly recommend using these optional training products to ensure an optimal learning experience. Sometimes there is only a practice exam or/and practice lab available.
Optional practice exam (trial exam)
To supplement this training course you may add a special practice exam. This practice exam comprises a number of trial exams which are very similar to the real exam, both in terms of form and content. This is the ultimate way to test whether you are ready for the exam.
Optional practice lab
To supplement this training course you may add a special practice lab. You perform the tasks on real hardware and/or software applicable to your Lab. The labs are fully hosted in our cloud. The only thing you need to use our practice labs is a web browser. In the LiveLab environment you will find exercises which you can start immediately. Thelab enviromentconsist of completenetworks containing for example,clients, servers,etc. This is the ultimate way to gain extensive hands-on experience.
