Maxim Gekk created SPARK-31563: ---------------------------------- Summary: Failure of InSet.sql for UTF8String collection Key: SPARK-31563 URL: https://issues.apache.org/jira/browse/SPARK-31563 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.4.5, 3.0.0, 3.1.0 Reporter: Maxim Gekk
The InSet expression works on collections of internal Catalyst's types. We can see this in the optimization when In is replaced by InSet, and In's collection is evaluated to internal Catalyst's values: [https://github.com/apache/spark/blob/branch-2.4/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/expressions.scala#L253-L254] {code:scala} if (newList.length > SQLConf.get.optimizerInSetConversionThreshold) { val hSet = newList.map(e => e.eval(EmptyRow)) InSet(v, HashSet() ++ hSet) } {code} The code existed before the optimization https://github.com/apache/spark/pull/25754 that made another wrong assumption about collection types. If InSet accepts only internal Catalyst's types, the following code shouldn't fail: {code:scala} InSet(Literal("a"), Set("a", "b").map(UTF8String.fromString)).sql {code} but it fails with the exception: {code} Unsupported literal type class org.apache.spark.unsafe.types.UTF8String a java.lang.RuntimeException: Unsupported literal type class org.apache.spark.unsafe.types.UTF8String a at org.apache.spark.sql.catalyst.expressions.Literal$.apply(literals.scala:88) at org.apache.spark.sql.catalyst.expressions.InSet.$anonfun$sql$2(predicates.scala:522) {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
