[jira] [Closed] (SPARK-10352) Replace SQLTestData internal usages
of String with UTF8String
[ https://issues.apache.org/jira/browse/SPARK-10352?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Feynman Liang closed SPARK-10352.
---------------------------------
Resolution: Not A Problem
Caused by my code not respecting {{InternalRow}} can only contain {{UTF8String}} and no {{java.lang.String}}
> Replace SQLTestData internal usages of String with UTF8String
> -------------------------------------------------------------
>
> Key: SPARK-10352
> URL: https://issues.apache.org/jira/browse/SPARK-10352
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Feynman Liang
>
> Running the code:
> {code}
> val inputString = "abc"
> val row = InternalRow.apply(inputString)
> val unsafeRow = UnsafeProjection.create(Array[DataType](StringType)).apply(row)
> {code}
> generates the error:
> {code}
> [info] java.lang.ClassCastException: java.lang.String cannot be cast to org.apache.spark.unsafe.types.UTF8String
> [info] at org.apache.spark.sql.catalyst.expressions.BaseGenericInternalRow$class.getUTF8String(rows.scala:46)
> ***snip***
> {code}
> Although {{StringType}} should in theory only have internal type {{UTF8String}}, we [are inconsistent with this constraint|https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/ScalaReflection.scala#L131] and being more strict would [break existing code|https://github.com/apache/spark/blob/master/sql/core/src/test/scala/org/apache/spark/sql/test/SQLTestData.scala#L41]
