      Description

      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
