Mostafa Mokhtar updated HIVE-10704: ----------------------------------- Assignee: Mostafa Mokhtar (was: Jason Dere) > Errors in Tez HashTableLoader when estimated table size is 0 > ------------------------------------------------------------ > > Key: HIVE-10704 > URL: https://issues.apache.org/jira/browse/HIVE-10704 > Project: Hive > Issue Type: Bug > Components: Query Processor > Reporter: Jason Dere > Assignee: Mostafa Mokhtar > Fix For: 1.2.1 > > Attachments: HIVE-10704.1.patch, HIVE-10704.2.patch > > > Couple of issues: > - If the table sizes in MapJoinOperator.getParentDataSizes() are 0 for all > tables, the largest small table selection is wrong and could select the large > table (which results in NPE) > - The memory estimates can either divide-by-zero, or allocate 0 memory if the > table size is 0. Try to come up with a sensible default for this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
