-----------------------------------
Summary: Function hour not working as expecte for hour 2
Key: SPARK-24545
URL: https://issues.apache.org/jira/browse/SPARK-24545
Project: Spark
Issue Type: Bug
Components: Java API
Affects Versions: 2.2.1
Reporter: Eric Blanco
Hello,
I tried to get the hour out of a date and it works except if the hour is 2.
Example:
from pyspark.sql.functions import *
columns = ["id","date"]
vals = [(4,"2016-03-27 02:00:00")]
df = sqlContext.createDataFrame(vals, columns)
df.withColumn("hours", hour(col("date"))).show()
+---+------------------+-----+
| id| date|hours|
+---+------------------+-----+
| 4|2016-03-27 2:00:00| 3|
+---+------------------+-----+
It works as expected for other hours.
