THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

Hopefully this is kind of a manual for a new starter to locate various components in source code.
Server Side
- Thrift IDL file for TCLIService: <BaseDir>/service-rpc/if/TCLIService.thrift (<BaseDir> is typically: <YourWorkspace>/hive/)
- TCLIService.Iface implemented by: org.apache.hive.service.cli.thrift.ThriftCLIService class
- ThriftCLIService subclassed by: org.apache.hive.service.cli.thrift.ThriftBinaryCLIService and org.apache.hive.service.cli.thrift.ThriftHttpCLIService for TCP mode and HTTP mode respectively.
org.apache.hive.service.cli.session.HiveSessionImpl class: Instance of this class are created on server side and managed by org.apache.accumulo.tserver.TabletServer.SessionManager instance.
- org.apache.hive.service.cli.SessionHandle class: instances of this class are returned from server to client and used by client for as input for Thrift API calls.org.apache.hive.service.cli.operation.Operation class: defines an operation (e.g. a query). Instances of this class are created on server and managed by org.apache.hive.service.cli.operation.OperationManager instance.
- org.apache.hive.service.auth.HiveAuthFactory class: a helper used by both HTTP and TCP mode for authentication. Refer to Setting Up HiveServer2 for various auth options.
Client Side
Interaction between client and server
- org.apache.hive.service.cli.SessionHandle class: instances of this class are returned from server to client and used by client for as input for Thrift API calls.
- org.apache.hive.service.cli.OperationHandle class: defines the operation handle which is part of of Operation and and used as a operation identifier. It's used by Thrift client to poll the execution status of an operation. org.apache.hive.service.auth.HiveAuthFactory class: a helper used by both HTTP and TCP mode for authentication. Refer to Setting Up HiveServer2 for various auth options.
