David Capwell commented on CASSANDRA-17072:
-------------------------------------------
Can you also work on a trunk patch? Executors were completely rewritten
> DebuggableThreadPoolExecutor does not propagate client warnings
> ---------------------------------------------------------------
>
> Key: CASSANDRA-17072
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17072
> Project: Cassandra
> Issue Type: Bug
> Components: Local/Other
> Reporter: Jacek Lewandowski
> Assignee: Jacek Lewandowski
> Priority: Normal
> Fix For: 4.1, 4.0.x
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Extracted this as a separate ticket per discussion on CASSANDRA-17044
> The problem is in {{DebuggableThreadPoolExecutor}} - it does not propagate
> executor locals to the thread when tracing is disabled. It is probably
> expected that we propagate the state if at least one executor local is
> defined, but we only check for tracing and completely ignore client warnings.
> The attached PR fixes the problem, adds some tests and reverts a workaround
> for client warnings in some schema alteration statements implemented in
> CASSANDRA-16296 (described below).
> ----
> h4. Old description - still valid, but this is just a manifestation of the
> problem rather than the problem itself
> This seemed to be screwed a bit. In just two schema alteration statements we
> collect client warnings which are captured during the transformation into a
> local collection.
> I guess it is done that way because the transformation is being executed in a
> different stage (migration) and client warnings collected in that stage are
> not present in the stage where the query is executed.
> Then, the client warnings are retrieved using {{clientWarnings}} method and
> added to the captured client warnings in the stage which is executing the
> query.
> This mechanism was implemented only in two schema alteration statements. It
> is possible that for other ones the client warnings can simply get lost.
