Pardon me I am new to ElasticSearch and hadoop.
I am trying to build GitHub - elastic/elasticsearch-hadoop: Elasticsearch real-time search and analytics natively integrated with Hadoop this repo locally . I did gradle distZip as mentioned in the instructions.
But I am facing the following error after running the command :
