-----------------------------------
Summary: Spark SQL support for Parquet with timestamp type field
Key: SPARK-4709
URL: https://issues.apache.org/jira/browse/SPARK-4709
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.1.0
Reporter: Felix Cheung
Priority: Critical
Have a data set on Parquet format (created by Hive) with a field of the
timestamp type. Reading this causes an exception:
val sqlContext = new org.apache.spark.sql.SQLContext(sc)
val p = sqlContext.parquetFile("hdfs:///data/parquetdata")
java.lang.RuntimeException: Potential loss of precision: cannot convert INT96
