Yin Huai created SPARK-11792:
--------------------------------
Summary: SizeEstimator cannot provide a good size estimation of
UnsafeHashedRelations
Key: SPARK-11792
URL: https://issues.apache.org/jira/browse/SPARK-11792
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Yin Huai
Assignee: Yin Huai
Priority: Blocker
At the executor side, SizeEstimator sees that an UnsafeHashedRelation has a
huge graph and produce a significant larger estimated size (compared with the
size of data stored in the UnsafeHashedRelation). So, the memory manger will
"think" we run out of memory after several broad cast joins.
