Summary: InputJobInfo in Pig UDFContext is heavyweight, and causes OOMs in Tez AMs Key: HIVE-17754 URL: https://issues.apache.org/jira/browse/HIVE-17754 Project: Hive Issue Type: Bug Components: HCatalog Affects Versions: 2.2.0, 3.0.0 Reporter: Mithun Radhakrishnan Assignee: Mithun Radhakrishnan HIVE-9845 dealt with reducing the size of HCat split-info, to improve job-launch times for Pig/HCat jobs. For large Pig queries that scan a large number of Hive partitions, it was found that the Pig {{UDFContext}} stored full-fat HCat {{InputJobInfo}} objects, thus blowing out the Pig Tez AM. Since this information is already stored in the {{HCatSplit}}, the serialization of {{InputJobInfo}} can be spared. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
