Method Detail

addHbaseResources

public static org.apache.hadoop.conf.Configuration addHbaseResources(org.apache.hadoop.conf.Configuration conf)

create

public static org.apache.hadoop.conf.Configuration create()

Creates a Configuration with HBase resources

Returns:

a Configuration with HBase resources

create

public static org.apache.hadoop.conf.Configuration create(org.apache.hadoop.conf.Configuration that)

Parameters:

that - Configuration to clone.

Returns:

a Configuration created with the hbase-*.xml files plus the given configuration.

merge

public static void merge(org.apache.hadoop.conf.Configuration destConf,
                         org.apache.hadoop.conf.Configuration srcConf)

Merge two configurations.

Parameters:

destConf - the configuration that will be overwritten with items from the srcConf

srcConf - the source configuration

isShowConfInServlet

public static boolean isShowConfInServlet()

Returns:

whether to show HBase Configuration in servlet

main

public static void main(String[] args)
                 throws Exception
