The Publish to SolrCloud CDH publisher will post documents to a SolrCloud index using a SolrJ Library. SolrJ has a CloudSolrClient class to communicate with SolrCloud. Instances of this class communicate with Zookeeper to discover Solr endpoints for SolrCloud collections and then perform requests.
This version of the publisher uses two approaches of connection:
- CloudSolrClient uses a Zookeeper host and port list.
- HttpSolrClient uses a unique Solr host and port.
For the Kerberos Authentication, this publisher uses a UserGroupInformation, which is a privileged action and the keytab, principal and hadoop core-site.xml to authenticate with Kerberos. It also uses a custom KerberizedHttpClient to perform the request.
