Hello Jalonso,
Following are steps that we usually use to uninstall. This may be little different for you depending on the ecosystem that you are using.
- Stop all services. You can do that manually or use the following:
$ for s in `cd /etc/init.d ; ls hadoop-*` ; do sudo service $s stop ; done
- If you choose to stop services manually then follow following order Hue, Sqoop, Flume, Oozie, Hive, HBase, MapRed, Yarn, HttpFS, HDFS and lastly Zookeeper.
- Then you can use following command to remove your environment specific components:
sudo yum remove hue
sudo yum remove pig
sudo yum remove sqoop
sudo yum remove flume
sudo apt-get purge hive hive-metastore hive-server hive-server2
sudo apt-get purge hadoop-hbase
sudo apt-get purge hadoop-zookeeper-server
sudo apt-get purge hadoop-zookeeper
sudo apt-get purge hadoop-hdfs-zkfc
apt-get purge hadoop-hdfs-hadoop-hdfs-journalnode
sudo apt-get purge hadoop-httpfs
sudo apt-get purge hadoop-0.20
- Post above steps you will have to clean up log files, config files, hue databases manually.
Hope that helps.
