[jira] [Commented] (CALCITE-4891) Avatica can't handle uuid fields saying 'Cannot handle class java.util.UUID as bytes'
[ https://issues.apache.org/jira/browse/CALCITE-4891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17445428#comment-17445428 ] Julian Hyde commented on CALCITE-4891: -- Do we have any tests for UUID fields? If not, this is basically a feature request, "Support UUID fields". I haven't checked the spec, but it seems reasonable to retrieve UUID fields (i.e. fields whose declared SQL type is UUID) as java.lang.String, java.util.UUID and byte[]. Any others? > Avatica can't handle uuid fields saying 'Cannot handle class java.util.UUID > as bytes' > - > > Key: CALCITE-4891 > URL: https://issues.apache.org/jira/browse/CALCITE-4891 > Project: Calcite > Issue Type: Bug > Components: avatica >Affects Versions: avatica-1.19.0 >Reporter: Jamie Taylor >Priority: Major > > When I try and fetch a value of type UUID through an avatica proxy I get an > error saying 'Cannot handle class java.util.UUID as bytes' > If I change the serilisation from json to protobuf I still get the exact same > error. > Other types that aren't supported such as blob give messages saying they > aren't supported, which makes this look like a bug. -- This message was sent by Atlassian Jira (v8.20.1#820001)

We coerce the UUID to bytes (or a utf-8 string) when sending that over the wire, so this error sounds like we messed up the wrapping/unwrapping across the wire. Do you have any aspirations to try to fix this? Seeing if we can write a simple unit test would be a good start – I would look at adding a test method to [RemoteMetaTest|https://github.com/apache/calcite-avatica/blob/master/server/src/test/java/org/apache/calcite/avatica/remote/RemoteMetaTest.java] > Avatica can't handle uuid fields saying 'Cannot handle class java.util.UUID > as bytes' > - > > Key: CALCITE-4891 > URL: https://issues.apache.org/jira/browse/CALCITE-4891 > Project: Calcite > Issue Type: Bug > Components: avatica >Affects Versions: avatica-1.19.0 >Reporter: Jamie Taylor >Priority: Major > > When I try and fetch a value of type UUID through an avatica proxy I get an > error saying 'Cannot handle class java.util.UUID as bytes' > If I change the serilisation from json to protobuf I still get the exact same > error. > Other types that aren't supported such as blob give messages saying they > aren't supported, which makes this look like a bug. -- This message was sent by Atlassian Jira (v8.20.1#820001)
