How to get the current local time or system time in spark-scala dataframe?

问题

I am trying to get the local time in spark-scala but it is returning UTC.

I am using java.time.LocalDateTime to get the current timestamp. But its returning the UTC standard.

java.sql.Timestamp.valueOf(DateTimeFormatter.ofPattern("YYYY-MM-dd HH:mm:ss.SSSSSS").format(LocalDateTime.now))

The LocalDateTime is returning local time in spark shell, but in my code it is giving UTC standard.

val time: LocalDateTime = LocalDateTime.now

How to get the current time?

The current output is UTC. I need the local time. I need to change the zone.

回答1:

Use current_timestamp() in org.apache.spark.sql.fuctions, this gives local time.
