To start your server, HCatalog needs to know where Hive is installed. This is communicated by setting the environment variable HIVE_HOME to the location you installed Hive. Start the HCatalog server by switching directories to root and invoking "HIVE_HOME=hive_home sbin/hcat_server.sh start". (In a Hive 0.11+ installation, this is "HIVE_HOME=hive_home hcatalog/sbin/hcat_server.sh start".)

Logging

Server activity logs are located in root/var/log/hcat_server. Logging configuration is located at root/conf/log4j.properties. Server logging uses DailyRollingFileAppender by default. It will generate a new file per day and does not expire old log files automatically.

...

To stop the HCatalog server, change directories to the root directory and invoke "HIVE_HOME=hive_home sbin/hcat_server.sh stop". (In a Hive 0.11+ installation, this is "HIVE_HOME=hive_home hcatalog/sbin/hcat_server.sh stop".)

Client Installation

Select a root directory for your installation of HCatalog client. We recommend /usr/local/hcat. If necessary, create the directory.

...

The HCatalog command line interface (CLI) can now be invoked as "HIVE_HOME=hive_home root/bin/hcat". (In a Hive 0.11+ installation, this is "HIVE_HOME=hive_home root/hcatalog/bin/hcat".)
