Hbase Scan example - scan table from "2012-05-09-09-35-192.168.0.0" to "2012-05-09-09-40-192.168.0.0" with row keys.- Filter row key which has string "192.168.210.10" source code package org.hadoop.dna.analyzer;import java.io.IOException; import org.apache.hadoop.conf.*;import org.apache.hadoop.fs.Path;import org.apache.hadoop.hbase.HBaseConfiguration;import org.apache.hadoop.hbase.client.Get;im..

Fetch data from HTable - Create Get instance with Row Key "rowkey1"Get get = new Get(Bytes.toBytes("rowkey1")); - Specify column family ("sig:botnet")get.addColumn(Bytes.toBytes("sig"), Bytes.toBytes("botnet"));Result result = htable.get(get); - Get value of column family (sig:botnet ==> value)byte[] val = result.getValue(Bytes.toBytes("sig"), Bytes.toBytes("botnet"));System.out.println("Value:"..

Insert Data into HTable - Create Put instance with Row Key "rowkey1"Put put = new Put(Bytes.toBytes("rowkey1")); - Insert data with Colume Family with "sig" & "botnet", then the value as "sobic"put.add(Bytes.toBytes("sig"), Bytes.toBytes("botnet"), Bytes.toBytes("sobic")); - insert data into htablehtable.put(put); Source code package org.hadoop.dna; import java.io.IOException; import org.apache...

Now we will make HBase table in Eclipse. Step 1. Create Java Class file Step 2. fill information .Package: the package name for your code (any name is OK) .Name : Your Java Class name (any name is OK) .Check "public static void main...." Source Code package org.hadoop.dna; import java.io.IOException; import org.apache.hadoop.conf.*;import org.apache.hadoop.fs.Path;import org.apache.hadoop.hbase...

This example shows how to create hbase project in Eclipse. Step 1. Open new java projectFile -> New -> Java Project Step 2. Enter project name (ex. SnortTable) -> Click "Next" for load external library Step 3. Add External JARs for compile . hbase-xxx.jar (in $HBASE_HOME) . common-logging-xxx.jar (in $HBASE_HOME/lib) . log4j-xxx.jar (in $HBASE_HOME/lib) . zookeeper-xxx.jar (in $HBASE_HOME/lib) ...
