I want to write RDD
to MYSQL
, which RDD
contains java.util.Date
type.
rdd.map(f=> FeatureData(
f.get("name").toString,
f.get("value").toString.toDouble,
f.get("time").asInstanceOf[Date],
f.get("period").toString))
.toDF()
In this RDD
the key of time
's value type is also java.util.Date
and it just get the error of [See nested exception: java.lang.UnsupportedOperationException: Schema for type java.util.Date is not supported
At first convert java.util.Date to java.sql.Date . Then run your sql with the data of java.sql.Date . Sample code :
java.util.Date utilDate = new java.util.Date();
java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());
Update: AndreHolzner suggested to use java.sql.Timestamp
. I did not try it yet, but generally Timestamp
is better than Date
.
