INLINE COMMENTS
  ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDFLeadLag.java:98 Shouldn't the
default value of amt be 1 ?
  ql/src/test/queries/clientpositive/windowing_expressions.q:38 It will be good to add a testcase
which exercises non-default values like sum(lag(p_retailprice,3,29.43))
