Apache Spark reassigned SPARK-7153:
-----------------------------------
Assignee: Apache Spark
> support Long type ordinal in GetItem
> ------------------------------------
>
> Key: SPARK-7153
> URL: https://issues.apache.org/jira/browse/SPARK-7153
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Wenchen Fan
> Assignee: Apache Spark
>
> In GetItem, we will cast the ordinal into Int first. However, if the ordinal
> is Long type, execution will fail even the value of ordinal meets the
> requirement. The reason is boxing. In java, we can convert long to int, but
> can't convert Long to Integer.
> {code}
> test("get item") {
> jsonRDD(sparkContext.makeRDD(
> """{"a": [1,2,3], "b": 2}""" :: Nil)).registerTempTable("t")
> checkAnswer(sql("SELECT a[b] FROM t"), Row(3))
> }
> {code}
> This test will fail as "b" is inferred as Long type.
