Rohith Sharma K S commented on SLIDER-954:
------------------------------------------
I googled for the Error: *'NoneType' object has no attribute 'strip'*.. It look
like some issue in kazoo client python implementation which is available in
slider-agent.tar.gz.
To confirm, i wrote simple test.py connecting ZK using kazoo modules available
in slider-agent.
*test.py :*
{code}
#!/usr/bin/env python
from kazoo.client import KazooClient
zk = KazooClient(hosts='10.18.130.110:54000')
zk.start()
print "Hello, Python!";
{code}
*output :*
{code}
rohith@host-10-18-130-110:~/os> python test.py
Traceback (most recent call last):
File "test.py", line 3, in <module>
zk = KazooClient(hosts='10.18.130.110:54000')
File "/home/rohith/os/kazoo/client.py", line 183, in __init__
self.set_hosts(hosts)
File "/home/rohith/os/kazoo/client.py", line 367, in set_hosts
self.hosts, chroot = collect_hosts(hosts, randomize_hosts)
File "/home/rohith/os/kazoo/hosts.py", line 22, in collect_hosts
result.append((host.strip(), port))
AttributeError: 'NoneType' object has no attribute 'strip'
