gaurav created SPARK-9592:
-----------------------------
Summary: First and Last aggregates are calculating the values for
entire DataFrame partition not on GroupedData partition.
Key: SPARK-9592
URL: https://issues.apache.org/jira/browse/SPARK-9592
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.4.0, 1.5.0
Reporter: gaurav
Priority: Minor
Fix For: 1.5.0
In current implementation, First and Last aggregates were calculating the
values for entire DataFrame partition and then the same value was returned for
all GroupedData in the partition.
sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/aggregates.scala
Fixed the First and Last aggregates should compute first and last value per
GroupedData instead of entire DataFrame.
