Spark SQL Unsupported datatype TimestampType

Question

I am just new to spark and scala.Trying to read a text file and save its a parquet file. For me one of the field I am using is the TimeStamp and its the docs say the spark1.1.0 supports java.util.TimeStamp.

The run time error I am getting while saving to parquet files is

Exception in thread "main" java.lang.RuntimeException: Unsupported datatype TimestampType at scala.sys.package$.error(package.scala:27) at org.apache.spark.sql.parquet.ParquetTypesConverter$$anonfun$fromDataType$2.apply(ParquetTypes.scala:301)

Any recommendation is really appreciable.

Thanks

This is actually a known bug of versions prior to 1.3.0 : https://issues.apache.org/jira/browse/SPARK-4987

A pull request has been already merged : https://github.com/apache/spark/pull/3820 but it won't be available before 1.3.0 is released.

If you're in a rush, you can build the master branch of 1.3.0 locally, otherwise you might have to wait, but there's hope because the RC2 of Spark 1.3.0 began to be voted as the final version yesterday, so if everything's ok with the candidate version, things can move quite fast.
