 Connection String

-Because the JackHare incorporates with two datastores, one is target noSQL DB, other is metadata store, so the connection string is a little bit of complicated. let's take look at it !!

+Because the JackHare incorporates with two datastores, one is target noSQL DB, another is metadata store, so the connection string is a little bit of complicated. let's take look at it !!
+
 _jdbc:jackhare:\[**noSqlconnectionString**\]:metastore:\[**metaDataStoreConnectionString**\]_
 
 The variables described as follows...
 
 **_noSqlconnectionString_**: the connection string link to the target noSQL DB
 
 **_metaDataStoreConnectionString_**: the connection string link to the metadata store
 
 For example, if the target noSQL DB is HBase, and the metadata store is Derby by default, the connection string would be...
 
-_jdbc:jackhare:hbase://192.168.1.50:metastore:jdbc:derby://localhost/derbyTestDb_
+_jdbc:jackhare:hbase://192.168.1.50?SCHEMA=TEST_SCHEMA&SCHEMA_CREATE=true:metastore:jdbc:derby://localhost/derbyTestDb_
+
+(The properties SCHEMA and SCHEMA_CREATE of metadata store are both optional)
 
 __NOTICE__
 
 The connection strings for both target noSQL DB and metadata store, follow the specifications defined by it's corresponding data store. JackHare just simply redirects the connection string to the corresponding data store server, so you can put any extra-parameters needed for your data store for any purpose :)

 CREATE CONNECTION
 ------------------------
 You can use two _java.sql.DriverManager.getConnection_ methods to create _java.sql.Connection_.
 
 By default, you can call getConnection method with three arguments, connectionString, userName and password as follows...
 
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 :::java
 Connection conn = null;
 conn = DriverManager.getConnection(CONNECTION_STRING, USER_NAME, PASSWORD);
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-If you want to set more parameters to the target noSQL DB, you can use another method as follows...
