Hi,
My supervisor keeps getting disconnected from the zookeeper and it prints
the following error -

Do I need to change any settings in the zookeeper config to fix this???
My zoo.cfg contains the following -
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper
clientPort=2181
This looks like a sync error. I am using tick tuples in my bolt to print to
a file after every three seconds. Could this interfere in some way with the
connection? I should mention that earlier this topology was working fine.
And then one day storm just stopped processing tuples for this topology.
Please help me out here.
Thanks,
Palak
