Table increments 6
This post provides a proof of concept of data collection from HTTP client into HBase. In this post, we will setup a flume agent with HTTP Source, JDBC Channel and AsyncHBase Sink. Initially we concentrate on POC of HTTP client data collection into HBase and at the end of this […]

Data Collection from HTTP Client into HBase


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.log 2
As discussed in previous post, we will discuss in detail about the properties in flume agent configuration properties. For ease of understanding, we will consider the same flume.conf file created in our previous post. Flume agent configuration file flume.conf resembles a Java property file format with hierarchical property settings. Here the […]

Flume Agent Configuration


Stop Agent 3
In this post, we will discuss about setting up of simple flume agent using Netcat as source and Console as sink. In this example of single-node Flume deployment, we create a Netcat source which listens on a port (localhost:44444) for network connections and logger sink type to log network traffic to console. […]
