python hbase exception

Question

when i use client.mutateRow(self.tableName, row, mutations) to write data to hbase . there is a exception,

IOError: IOError(message="Trying to contact region server Some server, retryOnlyOne=true, index=0, islastrow=true, tries=9, numtries=10, i=0, listsize=1, region=test,,1276665207312 for region test,,1276665207312, row 'hello', but failed after 10 attempts.\nExceptions:\n")

and i found the hbase's log. it tell me 10/06/16 17:31:25 ERROR server.TThreadPoolServer: Thrift error occurred during processing of message. org.apache.thrift.protocol.TProtocolException: Missing version in readMessageBegin, old client?

i use http://pypi.python.org/pypi/hbase-thrift/0.20.4 to write hbase. seems it is a library bug. anyone can help me ?
