# hive-custom-hook

Example on how to implement a hive hook

## Build jar with dependencies

```bash

mvn assembly:assembly

```

## Register your hook in Hive (Permanently, stays even if you restart)

```bash

# Open the file

vi /opt/hive/conf/hive-env.sh

# At the end of the file, add the line and save:

export HIVE_AUX_JARS_PATH=/hive-custom-hook-1.0-SNAPSHOT-jar-with-dependencies.jar

# Open the file

vi /opt/hive/conf/hive-site.xml

# Add the tag before the closing configuration tag  and save:

hive.exec.post.hookscom.medium.hive.hook.CustomHook

# Restart your Hive server

```

## Register your hook in Hive manually (For testing purposes, if your restart its cleared)

```bash

# Inside your Hive shell, run

ADD JAR /hive-custom-hook-1.0-SNAPSHOT-jar-with-dependencies.jar

set hive.exec.post.hooks=com.medium.hive.hook.CustomHook;

```
