Installing Hive from vendor packages
Right now, many companies, such as Cloudera, MapR, IBM, and Hortonworks, have packaged Hadoop into more easily manageable distributions. Each company takes a slightly different strategy, but the consensus for all of these packages is to make Hadoop easier to use for enterprise. For example, we can easily install Hive from Cloudera Distributed Hadoop (CDH), which can be downloaded from http://www.cloudera.com/content/cloudera/en/downloads/cdh.html.
Once CDH is installed to have the Hadoop environment ready, we can add Hive to the Hadoop cluster by following a few steps:
- Log in to the Cloudera manager and click on the dropdown button after the cluster name to choose Add a Service.
Cloudera manager main page
- In the first Add Service Wizard page, choose Hive to install.
- In the second Add Service Wizard page, set the dependencies for the service. Sentry is the authorization policy service for Hive.
- In the third Add Service Wizard page, choose the proper hosts for HiveServer2, Hive Metastore Server, WebHCat Server, and Gateway.
- In the fourth Add Service Wizard page, configure Hive Metastore Server database connections.
- In the last page of Add Service Wizard, review the changes on the Hive warehouse directory and metastore server port number. Keep the default values and click on the Continue button to start installing the Hive service. Once it is complete, close the wizard to finish the Hive installation.
