- This is for bigtop-0.2.0 where hadoop-hive, hadoop-hive-server, and hadoop-hive-metastore are installed automatically because the hive services start with the word hadoop. For bigtop-0.3.0 if you use the sudo apt-get install hadoop* command you won't get the Hive components installed.
Create the HDFS directories Hive needs
The Hive Post install scripts should create the /tmp and /user/hive/warehouse directories. If they don't exist, create them in HDFS.No Format hadoop fs -mkdir /tmp hadoop fs -mkdir /user/hive/warehouse hadoop -chmod g+x /tmp hadoop -chmod g+x /user/hive/warehouse
- If the post install scripts didn't create directories /var/run/hive and /var/lock/subsus, create directory /var/run/hive and create directory /var/lock/subsys
No Format sudo mkdir /var/run/hive sudo mkdir /var/lock/subsys #
- start the Hive Server
No Format sudo /etc/init.d/hadoop-hive-server start
- create a table in Hive and verify it is there
No Format $hive
hive>create table doh(id int);
hive>show tables;
Where to go from here
It is highly recommended that you read documentation provided by the Hadoop project itself (http://hadoop.apache.org/common/docs/r0.20.205.0/) Bigtop 0.2 or https://hadoop.apache.org/common/docs/r1.0.0/ for Bigtop 0.3 and that you browse through the Puppet deployment code that is shipped as part of the Bigtop release (bigtop-deploy/puppet/modules, bigtop-deploy/puppet/manifests).
