    Resolution: Not a Problem

Hi [~thaniyarasu],

this is very likely not a problem within Thrift itself. The message indicates, that the Thrift server you are calling does not know the method called. The two most likely causes for this problem you are:

 - you picked the wrong Thrift IDL file, or the service runs with the "wrong" API 
 - you run an hbase version earlier than 0.94.0 (see HBASE-1744)

HBase has two different Thrift APIs. The Thrift IDL, for the *old* API file is located in the folder {{src/main/resources/org/apache/hadoop/hbase/thrift/hbase.thrift}} 
without the "2". The HBase service function {{exists}} that you want to use has been added with HBASE-1744 to the *new* API, which is described in the Thrift file {{src/main/resources/org/apache/hadoop/hbase/thrift2/hbase.thrift}} 
that's the one with the "2" that you use with the client above. 

More details, including how to configure HBase accordingly, can be found [in this SO thread|http://stackoverflow.com/questions/22874861/hbase-thrift-in-cdh-5/22878870#22878870].
