Tables

You can use the getTables method of the DatabaseMetaData interface to retrieve a list of tables:

String connectionString = "jdbc:hdfs:Host=sandbox-hdp.hortonworks.com;Port=50070;Path=/user/root;";

Connection conn = DriverManager.getConnection(connectionString);
DatabaseMetaData table_meta = conn.getMetaData();
ResultSet rs=table_meta.getTables(null, null, "%", null);  
while(rs.next()){
  System.out.println(rs.getString("TABLE_NAME"));
}
The getTables method returns the following columns:

Column NameData TypeDescription
TABLE_CATStringThe table catalog.
TABLE_SCHEMStringThe table schema.
TABLE_NAMEStringThe table name.
TABLE_TYPEStringThe table type.
REMARKSStringThe table description.
