class HBaseOperations(object):

ROBOT_LIBRARY_SCOPE = 'TEST_SUITE'
ROBOT_LIBRARY_VERSION = '1.0.0'

def __init__(self, thrift_host=None,port=9090):
 self._conn = None

def query_table(table_name):
 pass
result1 = query_table('table_name1')
time.sleep(300)
when query_table('table_name2')
the query table will report an error:
TTransportException: TTransportException(type=4, message='TSocket read 0 bytes')
File "D:\Programs\Python\Python36\lib\site-packages\thriftpy2\transport\socket.py", line 132, in read
