"org.apache.drill.exec.store.sys.zk.ZkPStoreProvider" is default <https://github.com/apache/incubator-drill/blob/master/exec/java-exec/src/main/resources/drill-module.conf#L98> for distributed mode and you need not specify it explicitly.
If you want to use HBase storage instead, you can specify " org.apache.drill.exec.store.hbase.config.HBasePStoreProvider <https://github.com/apache/incubator-drill/blob/master/contrib/storage-hbase/src/main/java/org/apache/drill/exec/store/hbase/config/HBasePStoreProvider.java>" as the storage provider as follow sys.store.provider: { > class: "org.apache.drill.exec.store.hbase.config.HBasePStoreProvider", > hbase: { > tableName : "drill_store", > config : { > "hbase.zookeeper.quorum" : "localhost", > "hbase.zookeeper.property.clientPort" : 2181 > } > } > } > The provider class is part of "drill-storage-hbase" project.
