Hi Alexei,
I think this is more of a Kazoo lock recipe question and not ZooKeeper
specific, but I did some research for you:
It seems that Kazoo locks are based on the path parameter that you specify
when creating a new lock object and _not_ the identifier (name in your
case). So basically second call (should) timeouts, because you're trying to
acquire the same lock 10 times. Changing the code to use PATH as a prefix
and concatenate with the random name fixes it:
PATH = "aggregator_test/"
lock = zoo_conn.Lock(PATH + name)
Regards,
Andor
