ATTACHMENT ID: 12868055 - PreCommit-HIVE-Build > Hive on Spark generate more shuffle data than hive on mr > -------------------------------------------------------- > > Key: HIVE-15104 > URL: https://issues.apache.org/jira/browse/HIVE-15104 > Project: Hive > Issue Type: Bug > Components: Spark > Affects Versions: 1.2.1 > Reporter: wangwenli > Assignee: Rui Li > Attachments: HIVE-15104.1.patch, HIVE-15104.2.patch > > > the same sql, running on spark and mr engine, will generate different size > of shuffle data. > i think it is because of hive on mr just serialize part of HiveKey, but hive > on spark which using kryo will serialize full of Hivekey object. > what is your opionion? -- This message was sent by Atlassian JIRA (v6.3.15#6346)
