URL: https://issues.apache.org/jira/browse/KYLIN-947
Project: Kylin
Issue Type: Bug
Affects Versions: v0.8.1
Reporter: hongbin ma
Assignee: ZhouQianhao
It seems kafka is failing to fetch a offset that is exactly between startoffset
and endoffset, which should not happen at all
15/08/13 21:25:21 INFO streaming.StreamingUtil: topic:
Trkng.druid-sessionEvent, partitionId: 1, try to find closest offset with
timestamp: 1439498100000 between offset {4476901430, 4479189591}

partitionId: 1, target timestamp: 1439498100000
