---------------------------------
Summary: kafka.server.OffsetCheckpoint found inconsistant offset entry count, lead to NotAssignedReplicaException
Key: KAFKA-2575
URL: https://issues.apache.org/jira/browse/KAFKA-2575
Project: Kafka
Issue Type: Bug
Components: kafka streams
Affects Versions: 0.8.2.1
Reporter: Warren Jin
We have more than 100 topics in production, the default partition number is 24 for each topic.
We noticed the following errors in recent days.

I checked the kafka source code, the replication manager write the offsets of all the partitions to replication-offset-checkpoint every 5 seconds, and it has the internel lock for this file for every OffsetCheckpoint, it shoud be impossible that the offset count is 3918, but the actual count of offset entries is 3904? Is it the multihread issue that some other thread flush the content to the same file due to the internal lock in OffsetCheckPoint.
