Installation from Tarball

HCatalog Installed with Hive

Hcatalog command line

If you install Hive from the binary tarball, the hcat command is available in the hcatalog/bin directory.

Hcat command line is similar to 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, such as 'show tables'. 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. The HCatalog CLI is documented here and the Hive CLI is documented here.

Hive installation is documented here.

hcatalog client jars

In the hive tar.gz, hcatalog libraries are available under hcatalog/share/hcatalog/

Hcatalog server

Hcatalog server is same as hive metastore. You can just follow the hive metastore documentation for setting it up. However, if you would like to use the hcatalog scripts for running hive metastore, you can use the following instructions.
