Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The "Hbase/Scala" page has been changed by tuxracer69. The comment on this change is: starting a scala page (there was already a jython and groovy page). http://wiki.apache.org/hadoop/Hbase/Scala -------------------------------------------------- New page: == Accessing HBase from Scala == Scala can call Hbase classes very easily as other JVM based languages (Jython, Jruby, Groovy). Scala may be a better choice than say Jython as Jython 2.5.1 does not ship any more with a jythonc compiler command, and if you want to do Hbase mapreduce integration, you will need compiled classes. == Setting Your Classpath == Set your classpath as described in [[Hbase/Jython]] for instance getting it from: {{{ ps auwx|grep java|grep org.apache.hadoop.hbase.master.HMaster|perl -pi -e "s/.*classpath //" }}} == The Code == Please look at the Java API. Adaptation to scala should be relatively easy. The example below shows part of the smple Java code adapted to scala: {{{ import org.apache.hadoop.hbase.HBaseConfiguration import org.apache.hadoop.hbase.client.HBaseAdmin import org.apache.hadoop.hbase.client.HTable import org.apache.hadoop.hbase.client.Put import org.apache.hadoop.hbase.client.Get import org.apache.hadoop.hbase.util.Bytes val conf = new HBaseConfiguration() val admin = new HBaseAdmin(conf) // list the tables val listtables=admin.listTables() listtables.foreach(println) // let's insert some data in 'mytable' and get the row val table = new HTable(conf, "mytable") val theput= new Put(Bytes.toBytes("rowkey1")) theput.add(Bytes.toBytes("ids"),Bytes.toBytes("id1"),Bytes.toBytes("one")) table.put(theput) val theget= new Get(Bytes.toBytes("rowkey1")) val result=table.get(theget) val value=result.value() println(Bytes.toString(value)) }}}
