Hive Table Mapping with HBase 18
In this post, we will discuss about the setup needed for HBase Integration with Hive and we will test this integration with the creation of some test hbase tables from hive shell and populate the contents of it from another hive table and finally verify these contents in hbase table. […]

Hbase sink op 5
We will discuss about collection of data into HBase directly through flume agent. In our previous posts under flume category, we have covered setup of flume agents for file roll, logger and HDFS sink types. In this, we are going to explore the details of HBase sink and its setup […]

Flume Data Collection into HBase

In Hbase cluster, we can start hbase daemons with start-hbase.sh command or [crayon-588289b1e3a82468041319/] But in pseudo distribution mode (hbase.cluster.distributed=false), only HMaster daemon will be triggered but not the HRegionServer daemon or HQuorumPeer daemon. When we start the daemons with start-hbase.sh or individual hbase-daemon.sh commands for region server will not trigger daemon because […]

Hbase Daemons in Pseudo Distribution Mode

This post is a continuation for previous post on Hbase Installation. In the previous we have discussed about Hbase installation in pseudo distribution mode and in this post we will learn how to install and configure Hbase in fully distribution mode. Prerequisites:  JDK 1.6 or later versions of Java installed on […]
