-------------------------------------
Summary: ZK EPoll taking 100% CPU usage with Kafka Client
Key: KAFKA-479
URL: https://issues.apache.org/jira/browse/KAFKA-479
Project: Kafka
Issue Type: Bug
Environment: java 1.6.0_21
Kafka 0.7.14
Reporter: Chris Riccomini
Priority: Blocker
Hey Guys,
I'm seeing a very strange bug after I upgraded to Kafka 0.7.14. On my consumer
side, the process seems to run with very high CPU usage. I turned on HPROF, and
it's showing that 75% of the CPU usage is going to Java's NIO EPoll/select
calls.
There are supposedly work arounds that Mina and a few others employ. This seems
like more of a ZK bug- have you guys seen this before?
Any ideas?
