HCatalog Installed with Hive
| Info | ||
|---|---|---|
| ||
HCatalog is installed with Hive, starting with Hive release 0.11.0. |
If you install Hive from the binary tarball, the hcat command is available in the hcatalog/bin directory.
Alternatively, most hcat commands can be issued as hive commands, except for "hcat -g" and "hcat -p". Note that the hcat command uses the -p flag for permissions but hive uses it to specify a port number.
Hive installation is documented here.
Server Installation from Source

This information is adapted from the HCatalog 0.5.0 installation instructions. Now that HCatalog is part of the Hive project, it is installed with Hive and therefore much of the information below is obsolete. Furthermore, there is no such thing as "HCatalog 0.11.0" although that fiction has been substituted below for "HCatalog 0.5.0" — until this wikidoc is revised to reflect current realities, you should be skeptical of what you read here. |
Server Installation from Source
Prerequisites
- machine to put the installation tar on
- machine on which the server can be installed — this should have access to the Hadoop cluster in question, and be accessible from the machines you launch jobs from
- an RDBMS — we recommend MySQL and provide instructions for it
- Hadoop cluster
- Unix user that the server will run as, and, if you are running your cluster in secure mode, an associated Kerberos service principal and keytabs.
