> The spark v2.2.0 introduce TimeZoneAwareExpression, which causes bugs if we select data from a table with timestamp partitions.
> The steps to reproduce it:
> {code:java}
> spark.sql("create table test (foo string) parititioned by (ts timestamp)")
> spark.sql("insert into table test partition(ts = 1) values('hi')")
> spark.table("test").show()
> {code}
> The root cause is that TableReader.scala#230 try to cast the string to timestamp regardless if the timeZone exists.
> Here is the error stack trace
> {code}
> java.util.NoSuchElementException: None.get
