Description copied from interface: HS2ConnectionFileParser

Returns a Java properties object which contain the key value pairs which can be used in the Beeline connection URL

The properties returned must include url_prefix and hosts

Following are some examples of the URLs and returned properties object

• jdbc:hive2://hs2-instance1.example.com:10000/default;user=hive;password=mypassword should return [ "url_prefix"="jdbc:hive2://", "hosts"="hs2-instance1.example.com:10000", "defaultDB"=default, "user"="hive", "password"="mypassword" ]
• jdbc:hive2://zk-instance1:10001,zk-instance2:10002,zk-instance3:10003/default; serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2 should return [ "url_prefix"="jdbc:hive2://", "hosts"="zk-instance1:10001,zk-instance2:10002,zk-instance3:10003", "defaultDB"="default", "serviceDiscoveryMode"="zooKeeper", "zooKeeperNamespace"="hiveserver2" ]
• If hive_conf_list and hive_var_list is present in the url it should return a comma separated key=value pairs for each of them

  For example :

  jdbc:hive2://hs2-instance1.example.com:10000/default;user=hive?hive.cli.print.currentdb=true; hive.cli.print.header=true#hivevar:mytbl=customers;hivevar:mycol=id it should return [ "url_prefix"="jdbc:hive2://", "hosts"="hs2-instance1.example.com:10000", "defaultDB"="default", "user"="hive", "hiveconf"="hive.cli.print.currentdb=true, hive.cli.print.header=true", "hivevar"="hivevar:mytb1=customers, hivevar:mycol=id" ]
