HCatalog Installed with Hive

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 Now that HCatalog is part of the Hive project, it is installed with Hive and therefore much of the information below is obsolete.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. |

HCatalog Command Line
If you install Hive from the binary tarball, the hcat command is available in the hcatalog/bin directory.
The hcat command line is similar to the hive command line; the main difference is that it restricts the queries that can be run to metadata-only operations such as DDL and DML queries used to read metadata (for example, "show tables").
The HCatalog CLI is documented here and the Hive CLI is documented here.
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.
HCatalog Client Jars
In the Hive tar.gz, HCatalog libraries are available under hcatalog/share/hcatalog/.
HCatalog Server
HCatalog server is the same as Hive metastore. You can just follow the Hive metastore documentation for setting it up.
