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.
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.
In the Hive tar.gz, HCatalog libraries are available under hcatalog/share/hcatalog/.
HCatalog server is the same as Hive metastore. You can just follow the Hive metastore documentation for setting it up.
