Yang Ye created KAFKA-593:
-----------------------------
Summary: Empty log index file created when it shouldn't be empty
Key: KAFKA-593
URL: https://issues.apache.org/jira/browse/KAFKA-593
Project: Kafka
Issue Type: Bug
Reporter: Yang Ye
We have met empty index file during system test when it shouldn't be empty. In
this case, there're around 100 messages in each segment, each of size around
100 bytes, given the "logIndexIntervalBytes" 4096, there should be at least 2
log index entries, but we see empty index file. The kafka and zookeeper logs
are attached
