Installing and Upgrading the HCatalog RPM or Debian Packages

Installing the HCatalog RPM or Debian packages is more convenient than installing the HCatalog tarball because the packages:

  • Handle dependencies
  • Provide for easy upgrades
  • Automatically install resources to conventional locations

HCatalog comprises the following packages:

  • hive-hcatalog - HCatalog wrapper for accessing the Hive metastore, libraries for MapReduce and Pig, and a command-line program
  • hive-webhcat - A REST API server for HCatalog
  • hive-webhcat-server - Installs hive-webhcat and a server init script
