Hi,

I am using pyhs2 with HortonWorks Hadoop Image and am stuck at -

import pyhs2
with

pyhs2.connect(host='localhost',port=10000,authMechanism="PLAIN",user='root',password='hadoop',database='default')
as conn:
... with conn.cursor() as cur:
... print cur.getDatabases()
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.6/site-packages/pyhs2/__init__.py", line 7, in
connect
return Connection(*args, **kwargs)
File "/usr/lib/python2.6/site-packages/pyhs2/connections.py", line 36, in
__init__
transport.open()
File "/usr/lib/python2.6/site-packages/pyhs2/cloudera/thrift_sasl.py",
line 66, in open
message=("Could not start SASL: %s" % self.sasl.getError()))
thrift.transport.TTransport.TTransportException: Could not start SASL:
Error in sasl_client_start (-4) SASL(-4): no mechanism available: No worthy
mechs found

I have check and recheck that sasl is installed.

Any ideas why this happens?

Thanks,
Manish

I am guessing you are missing the plain kerb plugin. Try doing a:

yum install cyrus-sasl-plain

What auth are you using on HS2?

Thanks,
Brad

Thanks Brad. It worked great. I am not sure what auth i am using on Horton
Image. I have just set it up and started executing python programs via ssh
from the host.

Thanks,
Manish

my favourite game series of all time.

I tend to think of the Hive community as an elaborate video game.
