Once you’ve built the code from the HBase metastore patch, here’s how to make it run against HBase:
- Install HBase, you want preferably HBase 0.98 as that’s what we use internally.is being used for testing.

hive-common-1.*.jar
hive-metastore-1.*.jar
hive-serde-1.*.jar

- Set HADOOP_HOME if you’re not in a cluster where hadoop is already on your path.
- Start HBase: $HBASE_HOME/bin/start-hbase.sh
- Set it up so that HBase jars and conf file are picked up by Hive
- export HIVE_AUX_JARS_PATH=$HBASE_HOME/lib/
- export AUX_CLASSPATH=$HBASE_HOME/conf
- Create the metastore tables in HBase: hive --service hbaseschematool install
- Configure Hive to use HBase as its metastore, in hive-site.xml:
