What is the difference between Hadoop and Splunk?

Splunk Hadoop Connect provides bi-directional integration to move data between the Splunk platform and Hadoop. Deploy the Splunk platform for real-time collection, indexing, analysis, and visualizations and then forward events to Hadoop for archiving and additional batch analytics. You can also import data that is already stored in Hadoop.

With Splunk Hadoop Connect, you can:

Deliver events in their raw form or preprocessed from the Splunk platform to Hadoop Distributed File System (HDFS) or a mounted file system.

 Explore HDFS and your mounted file system.

Import data from HDFS into the Splunk platform at search or index time, if you are using the Splunk platform version 5.0 or later.

Features That Make Splunk the Google of Unstructured Data

1. Log processing is one of the core competencies of Splunk. It stores all your logs and provides very fast search capabilities roughly in the same way Google does for the internet device log files.
2. The Search Processing Language (SPL) for Splunk is an extremely powerful tool for extracting meaning out of vast amounts of data and performing statistical operations on what is relevant in a specific context.
3. Splunk Training in Jaipur indexes any kind of machine data that can be represented as text and there is no need to define tables and fields before you can store data. Splunk does not have a fixed schema. In fact, it performs field extraction at search time. This aspect allows for great flexibility.
4. Splunk does not reduce the granularity of older events, compressing many data points into one because of capacity limits. It can seamlessly index hundreds of terabytes per day and keep practically unlimited amounts of data.
5. Splunk dashboards allow you to monitor all of your systems at once, so when a problem occurs you can start looking for a solution even before the problem starts bothering the system, or even better, the Splunk dashboard allows to clearly look for signs of a possibly arising problem.
