> The change for IMPALA-1048 writes {{TRuntimeProfileNode.node_metadata}}
> unconditionally, even when both its fields are unset. This trips up the Java
> reader code, which expects to find exactly one type of a union to be set. The
> resulting error looks like this:
> {noformat}
> Caused by: org.apache.thrift.protocol.TProtocolException: Unrecognized type 0
