ProtocolError: No protocol version header

Question

I have hortonworks cluster with versions as below:

hbase = 1.1.2
happybase=1.1.0
hortonworks hadoop cluster = HDP-2.6.2.0

When I try to run simple example:

import happybase
server = "server-address"
connection = happybase.Connection(server)
print connection.tables()

I got this exception:

Traceback (most recent call last):
  File "/Users/psobolewski/hbase_urls.py", line 19, in <module>
    print connection.tables()
  File "/Library/Python/2.7/site-packages/happybase/connection.py", line 242, in tables
    names = self.client.getTableNames()
  File "/Library/Python/2.7/site-packages/thriftpy/thrift.py", line 198, in _req

Are you connecting to the right port as well as the right address? It seems unlikely your server's address really is "server-address" - what is the address really? — Tom Dalton, Feb 06 '18 at 10:45
Also, are you using the correct `transport` and `protocol` as per http://happybase.readthedocs.io/en/latest/api.html#connection ? — Tom Dalton, Feb 06 '18 at 10:48
@TomDalton i connect to the right address and port. Port is open for my host also. — Piotr Sobolewski, Feb 06 '18 at 16:05
Did you solve the issue? I have the same problem trying to put new data — dhalfageme, Mar 25 '19 at 08:10

Try to change port=2181 and check hbase-site.xml

Hi Samat. I think it would help if you would said in hbase-site.xml where did you find the port 2181 because normally the port 2181 doesn't mean that all people will use the same port. – lauralacarra Jan 05 '22 at 14:58
