HBase Thrift API

nhbaseapi's Issues

Error when trying to connect

I've used another Thrift API to connect to hbase previously, but now I'm trying NHBaseAPI. When I try to connect using:

string connectionStr = "zk=[my port]:2181";
IHBaseClient client = new HBaseClient(connectionStr);

I get the following error:

The following InnerException reported: System.TypeInitializationException: The type initializer for 'Gridsum.NHBaseThrift.Client.HBaseClient' threw an exception. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: The type initializer for 'Gridsum.NHBaseThrift.Contracts.ThriftObject' threw an exception. ---> System.TypeInitializationException: The type initializer for 'KJFramework.Tracing.TracingManager' threw an exception. ---> System.NullReferenceException: Object reference not set to an instance of an object.

Any suggestions of what may be wrong? I ca confirm my hbase instance is up because I can use HareDBClient to access the data in my hbase table.

Thanks.

Is there any plans for supporting filterString in ScannerOpenWithStopRequestMessage?

Just found this .Net based HBase client library but it still lacks of some features such as filters. It there any plan and timeline for supporting them?

Socket disconnected by remote server (Thrift server)

Does NHBaseAPI work with HBase 0.94? I found it always encounters the following error while using HTable.NewScanner() to do the query:

System.Net.Sockets.SocketException (0x80004005): An existing connection was forcibly closed by the remote host.
in System.Net.Sockets.Socket.Shutdown(SocketShutdown how)
in KJFramework.Net.Channels.Receivers.TcpAsynDataRecevier.Stop()
