Summary: Create Intermediate Flat Hive Table失败
Key: KYLIN-3616
URL: https://issues.apache.org/jira/browse/KYLIN-3616
Project: Kylin
Issue Type: Bug
Components: Environment
Affects Versions: v1.5.3
Reporter: LinRongRen
Fix For: v1.5.3
创建cube的时候,在Monitor模块观察,执行完第一步:Count Source Table
执行第二步:Create Intermediate Flat Hive Table出现错误Error
日志提示:
total input rows = 4541
expected input rows per mapper = 1000000
reducers for RedistributeFlatHiveTableStep = 1
