[jira] [Updated] (SPARK-12404) Ensure objects passed to
StaticInvoke is Serializable
[ https://issues.apache.org/jira/browse/SPARK-12404?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kousuke Saruta updated SPARK-12404:
-----------------------------------
Description:
Now `StaticInvoke` receives Any as a object and StaticInvoke can be serialized but sometimes the object passed is not serializable.
For example, following code raises Exception because RowEncoder#extractorsFor is invoked indirectly makes `StaticInvoke`.
<code>
case class TimestampContainer(timestamp: java.sql.Timestamp)
val rdd = sc.parallelize(1 to 2).map(_ => TimestampContainer(System.currentTimeMillis))
val df = rdd.toDF
val ds = df.as[TimestampContainer]
val rdd2 = ds.rdd <----------------- invokes extractorsFor indirectory
<code>
