-----------------------------------
Summary: The ephemeral node [%s] at %s has gone away while reading
it
Key: KAFKA-10088
URL: https://issues.apache.org/jira/browse/KAFKA-10088
Project: Kafka
Issue Type: Improvement
Components: core
Affects Versions: 0.10.2.3
Environment: Linux 3.10.0-693.2.2.el7.x86_64
Reporter: jinshaoling
Attachments: 1DF600B6-388B-4cd3-800F-93AD39323C3E.png
I use kafka 10.0.2 in the production environment, and a problem occurs: the
problem should be after the re-election of the controller. due to the
relatively large amount of data, the log is soon filled, and soon the alarm of
insufficient disk space appears . The log level used in our production
environment is "info", and the log is like this:
{code:java}
The ephemeral node [***] at *** has gone away while reading it {code}
I downloaded the source code of kafka from github and found in
kafka.utils.ZkUtils
CreateCallback#:
{code:java}
case Code.NODEEXISTS => zkHandle.getData(path, false, getDataCallback, null)
{code}
GetDataCallback#:
{code:java}
case Code.NONODE => info("The ephemeral node [%s] at %s has gone away while
reading it, ".format(data, path)) {code}
one case is Code.NODEEXISTS , but another case is Code.NONODE. I think this
problem should come from zookeeper, but I don’t know why?
Please help me, thanks!
