conn.cursor(): impala.error.HiveServer2Error

See original GitHub issue
  • impyla==0.14.0
  • Python 3.6

Sorry I am newbie on this. Any ideas?

from impala.dbapi import connect
conn = connect(host='my ip', port=21050) # it works
# or conn = connect(host='my ip', port=21000) # it works
cursor = conn.cursor() # raise an error
cursor = conn.cursor(user='some user') # raise an error
env/lib/python3.6/site-packages/impala/", line 125, in cursor
    session = self.service.open_session(user, configuration)
env/lib/python3.6/site-packages/impala/", line 998, in open_session
    resp = self._rpc('OpenSession', req)
env/lib/python3.6/site-packages/impala/", line 924, in _rpc
    response = self._execute(func_name, request)
env/lib/python3.6/site-packages/impala/", line 957, in _execute
impala.error.HiveServer2Error: Failed after retrying 3 times

Internally, it raise this error on this line session = self.service.open_session(user, configuration)
