Description:
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

org.apache.spark.sql.catalyst.expressions.BaseGenericInternalRow$class.getUTF8String(rows.scala:46)
