Recreating Hive metadata after decommissioning a node

After removing/decommissioning a node that stored the hive metadata, truncate the hive metadata table, then recreate the table. In the hive-site.xml, set the parameters as shown in the following example to specify a different keyspace and table for the Hive metastore:

<property>
    <name>cassandra.connection.metaStoreKeyspaceName</name>
    <value>newKeyspaceName</value>
  </property>
  <property>
    <name>cassandra.connection.metaStoreColumnFamilyName</name>
    <value>MetaStore</value>
  </property>

This action is necessary to prevent an exception in SemanticAnalyzer.genFileSinkPlan.
