Summary: LLAP: Fail map join tasks if hash table memory exceeds threshold Key: HIVE-16546 URL: https://issues.apache.org/jira/browse/HIVE-16546 Project: Hive Issue Type: Bug Components: llap Affects Versions: 3.0.0 Reporter: Prasanth Jayachandran Assignee: Prasanth Jayachandran When map join task is running in llap, it can potentially use lot more memory than its limit which could be memory per executor or no conditional task size. If it uses more memory, it can adversely affect other query performance or it can even bring down the daemon. In such cases, it is better to fail the query than to bring down the daemon. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
