--------------------------------
Summary: Hive Lead/Lag OLAP Not Functioning
Key: HIVE-4797
URL: https://issues.apache.org/jira/browse/HIVE-4797
Project: Hive
Issue Type: Bug
Components: OLAP
Affects Versions: 0.11.0
Environment: Linux version 2.6.18-308.24.1.el5
([email protected]) (gcc version 4.1.2 20080704 (Red
Hat 4.1.2-52))
Java 1.6.0_31
Hadoop 1.2.0
Hive 0.11.0
Reporter: Joshua Lee
Unable to use built in LAG/LEAD functionality. Following the example in
documentation at
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+WindowingAndAnalytics
leads to error. This leads me to believe that this is a bug rather than
something wrong with my query. Specifically:
-- Set up database
hive> create table lag_test(a int, b int, c string, d string) row format
delimited fields terminated by "\t";
-- load test data using local file
-- Run test query
hive> SELECT a, LEAD(a) OVER (PARTITION BY b ORDER BY C ROWS BETWEEN CURRENT
ROW AND 1 FOLLOWING) FROM lag_test; -- copied from documentation
FAILED: SemanticException Failed to breakup Windowing invocations into Groups.
At least 1 group must only depend on input columns. Also check for circular
dependencies.
Underlying error: Expecting left window frame boundary for function
LEAD((TOK_TABLE_OR_COL a))
org.apache.hadoop.hive.ql.parse.WindowingSpec$WindowSpec@39fe9830 as _wcol0 to
be unbounded. Found : 0
