Summary: UT: fix partition test case
Key: HIVE-8788
URL: https://issues.apache.org/jira/browse/HIVE-8788
Project: Hive
Issue Type: Sub-task
Components: Tests
Affects Versions: spark-branch
Reporter: Thomas Friedrich
Priority: Minor
The test limit_partition_metadataonly fails with
2014-11-06 18:40:12,891 ERROR ql.Driver (SessionState.java:printError(829)) -
FAILED: SemanticException Number of partitions scanned (=4) on table srcpart
exceeds limit (=1). This is controlled by hive.limit.query.max.table.partition.
org.apache.hadoop.hive.ql.parse.SemanticException: Number of partitions scanned
(=4) on table srcpart exceeds limit (=1). This is controlled by
hive.limit.query.max.table.partition.

In the test, SemanticAnalyzer.enforceScanLimits expects only 1 partition
ds=2008-04-08/hr=11 but gets 4 partitions:
[srcpart(ds=2008-04-08/hr=11), srcpart(ds=2008-04-08/hr=12),
srcpart(ds=2008-04-09/hr=11), srcpart(ds=2008-04-09/hr=12)]
In the log it shows that the ParitionPruner ran, and it should have only
retained one partition:
