Teng Qiu updated SPARK-2729:
----------------------------
Description:
after SPARK-2710 we can create a table in Spark SQL with ColumnType Timestamp
from jdbc.
when i try to
{code}
sqlContext.cacheTable("myJdbcTable")
{code}
then
{code}
sqlContext.sql("select count(*) from myJdbcTable")
{code}
i got exception:
{code}
scala.MatchError: 8 (of class java.lang.Integer)
at
org.apache.spark.sql.columnar.ColumnBuilder$.apply(ColumnBuilder.scala:146)
{code}
i checked the code ColumnBuilder.scala:146
it is just missing a match of Timestamp typeid.
so it is easy to fix.
