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.
