Michael Smith commented on IMPALA-13252:
----------------------------------------
Turns out Thrift types get their own operator<< overload based on printTo. We
could use that by creating an inherited type for TUniqueId, but that kind of
defeats the point of making printing transparent. With GCC the later overload
wins, but in Clang the first seems to win, so there's no reliable way to add
our own override. So I'll remove the overload, and go back to using PrintId
explicitly everywhere.

> Key: IMPALA-13252
> URL: https://issues.apache.org/jira/browse/IMPALA-13252
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 4.4.0
> Reporter: Michael Smith
> Assignee: Michael Smith
> Priority: Major
> Fix For: Impala 4.5.0
>
>
> Some error messages, such as
> {code}
> Filter update received for non-executing query with id:
> TUniqueId(hi=-8482965541048796556, lo=3501357296473079808)
> {code}
> print query id as the raw Thrift type rather than our colon-delimited format,
> e.g. "8a4673c8fbe83a74:309751e900000000". This makes it difficult to trace
> queries through logs.
> Normalize on the colon-delimited format.
