[jira] [Created] (CALCITE-2198) ClassCastException in RexBuilder when makeLiteral for BINARY and VARBINARY

Hequn Cheng created CALCITE-2198:
------------------------------------

             Summary: ClassCastException in RexBuilder when makeLiteral for BINARY and VARBINARY
                 Key: CALCITE-2198
                 URL: https://issues.apache.org/jira/browse/CALCITE-2198
             Project: Calcite
          Issue Type: Bug
          Components: core
            Reporter: Hequn Cheng
            Assignee: Julian Hyde


Currently, makeLiteral for {{BINARY}} and {{VARBINARY}} will throw {{ClassCastException}} when value type is {{byte[]}}:
{code:java}
java.lang.ClassCastException: [B cannot be cast to org.apache.calcite.avatica.util.ByteString
 at org.apache.calcite.rex.RexBuilder.makeLiteral(RexBuilder.java:1271)
 at org.apache.calcite.rex.RexBuilder.makeLiteral(RexBuilder.java:1251){code}
To avoid this exception we have to add support for type of  {{byte[]}}. One choice is to convert {{byte[]}} to {{ByteString}} in {{RexBuilder.clean()}}.
