Subject [jira] [Created] (HIVE-8788) UT: fix partition test case
Date Fri, 07 Nov 2014 23:17:34 GMT
Thomas Friedrich created HIVE-8788:
--------------------------------------

             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.
	at org.apache.hadoop.hive.ql.parse.SemanticAnalyzer.enforceScanLimits(SemanticAnalyzer.java:10358)
	at org.apache.hadoop.hive.ql.parse.SemanticAnalyzer.analyzeInternal(SemanticAnalyzer.java:10190)
	at org.apache.hadoop.hive.ql.parse.BaseSemanticAnalyzer.analyze(BaseSemanticAnalyzer.java:221)
	at org.apache.hadoop.hive.ql.Driver.compile(Driver.java:419)

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:
2014-11-07 14:18:09,147 DEBUG ppr.PartitionPruner (PartitionPruner.java:prune(206)) - Filter

(ds = '2008-04-08'))
