What is ElasticSearch Hadoop

Question

I am a Fresher to Hadoop Technology and I am trying to set up a simple Hadoop Cluster with 3 data nodes and 1 name node. The Cluster is successfully set up and now am having an issue with ElasticSearch. I have tried to install EclasticSearch on one of the data nodes and tried to access HDFS which was unsuccessful. The ElasticSearch and HDFS work perfectly when they are independent, but fail to work when I tried to collaborate them.

Please Help me out to set up the Cluster with ElasticSearch.

Answer 1

I suggest you go through this link and understand the technicalities first.

Later try the following steps:

• I suggest you try to use this repo.
• It's an Elasticsearch real-time search and analytics natively integrated with Hadoop and you can follow the documentation provided here to use it.
• The repo is provided by Elasticsearch.

I hope this resolves the issue.

Answer 2

it as a connector that allows data to flow bi-directionaly so that applications can leverage transparently the Elasticsearch engine capabilities to significantly enrich their capabilities and increase the performance.
