I am trying to bring Hive table data to Elasticsearch but it's failing to get this through, any help will be appreciated.
The error I get is "Unable to find class: org.elasticsearch.hadoop.hive.EsHiveInputFormat" and "FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask"
The hive engine is set to mr

Please make sure that ES-Hadoop is available on the job's classpath using the [installation instructions](https://www.elastic.co/guide/en/elasticsearch/hadoop/current/hive.html#_installation_2) for Hive. We've seen in the past that the best way to install is via the `ADD JAR` directive instead of relying on the Hive jar path settings.

Thanks James for you response. I have not tried to add it in the command line yet but I will try that and update the output.

ok James, it worked !!! Since I am planning to use script, I have added the es-hadoop modules to the command itself. Many thanks for you pointer and it helped me, I appreciate it. Still I have 2 more clarifications/questions from below output

1. why is the job getting killed as highlighted in above output?
2. How do I ensure to read continuously from Hive table and update in ES in same index.

I'm not sure I see the failure in your logs here, can you share the exact line that details the failure?
Reading continuously from Hive table and updating in ES will require a regularly scheduled Hive query to perform the updates. The ES Hive integration just creates an external table over the existing ES index. Since Hive is a batch tool, you'll need to do regular data synchronization on your own, or switch to a streaming library that can split the data between the two datastores
