Dear Wiki user, You have subscribed to a wiki page or wiki category on "Lucene-hadoop Wiki" for change notification.
The following page has been changed by JimKellerman: http://wiki.apache.org/lucene-hadoop/Hbase/FAQ The comment on the change is: escape camel case words so they are not interpreted as wiki words ------------------------------------------------------------------------------ [[Anchor(2)]] '''1. [#1 Can someone give an example of basic API-usage going against hbase?]''' - The two main client-side entry points are [http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/javadoc/org/apache/hadoop/hbase/HBaseAdmin.html H!BaseAdmin] and [http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/javadoc/org/apache/hadoop/hbase/HTable.html H!Table]. Use H!BaseAdmin to create, drop, list, enable and disable tables. Use it also to add and drop table column families. For adding, updating and deleting data, use HTable. Here is some pseudo code absent error checking, imports, etc., that creates a table, adds data, does a fetch of just-added data and then deletes the table. + The two main client-side entry points are [http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/javadoc/org/apache/hadoop/hbase/HBaseAdmin.html HBaseAdmin] and [http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/javadoc/org/apache/hadoop/hbase/HTable.html HTable].

These are probably your best source for sample code. Start with the code in org.apache.hadoop.hbase.TestH!BaseCluster. It does a general table setup and then performs various client operations on the created table: loading, scanning, deleting, etc. Don't forget your client will need a running hbase instance to connect to (See the ''Getting Started'' section toward the end of this [http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/javadoc/org/apache/hadoop/hbase/package-summary.html#package_description Hbase Package Summary] page).
