Zookeeper KeeperException #21

Open CarstenWalther opened 6 years ago

CarstenWalther commented 6 years ago

When starting the platform from a clean state, we get a bunch of Exceptions from Zookeeper: Example:

INFO  [ProcessThread(sid:0 cport:2181)::PrepRequestProcessor@653] - Got user-level KeeperException when processing sessionid:0x100013695880001 type:setData cxid:0x29 zxid:0x84 txntype:-1 reqpath:n/a Error Path:/config/topics/__consumer_offsets Error:KeeperErrorCode = NoNode for /config/topics/__consumer_offsets

These exceptions seem to not affect the price wars platform. It's not high priority, but it would be nice to get rid of these errors. I guess, there is some misconfiguration in our Kafka or Zookeeper.

These messages are not problematic according to this post . Should we change the logging level to hide them or ignore these messages?

Is the logging level set to warn? If so, I am fine with error

CarstenWalther commented 6 years ago

It is an info-level log message

Bouncner commented 6 years ago

Could you set the log level to warn or something similar?
