Hi John Z,
Did you tried running with latest Python 2.7.11 or 2.7.12?
Kind regards,
Rajesh Radhakrishnan

Subject: cqlsh fails to connect
I upgraded DSE 4.8.9 to 5.0.3, that is, from Cassandra 2.1.11 to 3.0.9
I used DSE 5.0.3 tarball installation. Cassandra cluster is up and running OK
and I am able to connect through DBeaver.
Tried a lot of things and cannot connect with cqlsh:
Connection error: ('Unable to connect to any servers', {'x.x.x.x':
UnicodeDecodeError('utf8',
'+\x00\x00H\x08\x00\xf0$+\x00\x00\x10\x7f-\xe7S+\x00\x00`B\xb3\xe5S', 6, 7,
'invalid continuation byte')})
Versions
------------
$ pip freeze | grep cas
cassandra-driver==3.6.0
cassandra-driver-dse==1.0.3
$ python
Python 2.7.5 (default, Nov 20 2015, 02:00:19)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
$ cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
$ which cqlsh (DSE's cqlsh client)
/opt/dse/bin/cqlsh
Tried also
$ export CQLSH_NO_BUNDLED=false
Also tried
--------------
Tried to install via pip in a fresh clean box the cqlsh client. I ended up with
the latest cassandra-driver 3.7.1
$ pip freeze | grep cas
cassandra-driver==3.7.1
$ pip freeze | grep cql
cql==1.4.0
cqlsh==5.0.3
And got this:
Connection error: ('Unable to connect to any servers', {'x.x.x.x':
ProtocolError("cql_version '3.3.1' is not supported by remote (w/ native
protocol). Supported versions: [u'3.4.0']",)})
Tried to force it:
$ cqlsh XX.XX.XX.XX --cqlversion="3.4.0"
Got the original-first error message:
Connection error: ('Unable to connect to any servers', {'x.x.x.x':
UnicodeDecodeError('utf8',
'+\x00\x00H\x08\x00\xf0$+\x00\x00\x10\x7f-\xe7S+\x00\x00`B\xb3\xe5S', 6, 7,
'invalid continuation byte')})
At some point I got this message too, but I don't remember what I did:
Connection error: ('Unable to connect to any servers', {'x.x.x.x':
DriverException(u'Failed decoding result column "table_name" of type varchar:
',)})
Thank you in advance for you help,
John Z
