public HBase()

Method Detail

version

public HBase version(String version)

Set the Apache HBase version to be used. Required.

Parameters:

version - HBase version. E.g., "1.4.3".

tableName

public HBase tableName(String tableName)

Set the HBase table name, Required.

Parameters:

tableName - Name of HBase table. E.g., "testNamespace:testTable", "testDefaultTable"

zookeeperQuorum

public HBase zookeeperQuorum(String zookeeperQuorum)

Set the zookeeper quorum address to connect the HBase cluster. Required.

Parameters:

zookeeperQuorum - zookeeper quorum address to connect the HBase cluster. E.g., "localhost:2181,localhost:2182,localhost:2183".

zookeeperNodeParent

public HBase zookeeperNodeParent(String zookeeperNodeParent)

Set the zookeeper node parent path of HBase cluster. Default to use "/hbase", Optional.

Parameters:

zookeeperNodeParent - zookeeper node path of hbase cluster. E.g, "/hbase/example-root-znode".

writeBufferFlushMaxSize

public HBase writeBufferFlushMaxSize(String maxSize)

Set threshold when to flush buffered request based on the memory byte size of rows currently added. Default to 2mb. Optional.

Parameters:

maxSize - the maximum size (using the syntax of MemorySize).

writeBufferFlushMaxRows

public HBase writeBufferFlushMaxRows(int writeBufferFlushMaxRows)

Set threshold when to flush buffered request based on the number of rows currently added. Defaults to not set, i.e. won't flush based on the number of buffered rows. Optional.

Parameters:

writeBufferFlushMaxRows - number of added rows when begin the request flushing.

writeBufferFlushInterval

public HBase writeBufferFlushInterval(String interval)

Set an interval when to flushing buffered requesting if the interval passes, in milliseconds. Defaults to not set, i.e. won't flush based on flush interval. Optional.

Parameters:

interval - flush interval. The string should be in format "{length value}{time unit label}" E.g, "123ms", "1 s", If no time unit label is specified, it will be considered as milliseconds. For more details about the format, please see TimeUtils.parseDuration(String)}.

properties

public HBase properties(Properties properties)

Sets the configuration properties for HBase Configuration. Resets previously set properties.

Parameters:

properties - The configuration properties for HBase Configuration.

property

public HBase property(String key,
                      String value)

Adds a configuration property for HBase Configuration.

Parameters:

key - property key for the HBase Configuration

value - property value for the HBase Configuration
