-----------------------------
Summary: SimpleFetchOptimizer needs to re-enable FS caching before
scanning dirs
Key: HIVE-8369
URL: https://issues.apache.org/jira/browse/HIVE-8369
Project: Hive
Issue Type: Bug
Components: Physical Optimizer
Affects Versions: 0.14.0
Reporter: Gopal V
SimpleFetchOptimizer spends a lot of CPU within itself because hive disables
HDFS fs caching (fs.hdfs.impl.disable.cache).
SimpleFetchOptimizer needs a revisit for its optimization rules, along with a
fix for this case.
