-------------------------------------------
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.
