---------------------------------------
Summary: Hive on Tez incorrect partition pruning ANALYZE TABLE
Key: HIVE-16412
URL: https://issues.apache.org/jira/browse/HIVE-16412
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 2.1.1
Environment: Hadoop2.7.3, Hive 2.1.1, Tez 0.8.5
Reporter: Amir Shenavandeh
Hive on Tez, on partitioned tables ANALYZE TABLE T PARTITION (...) COMPUTE
STATISTICS; will gather stats for all partitions from metastore even though
partition spec only chooses a subset. Hive on MR runs efficiently.
For example:
---
analyze table ext_data_part partition(a=9957) compute statistics noscan
---
Will cause:
---

and "DBS"."NAME" = ? ]
