> We are seeing those error messages for a testing query. The *taskId != partitionId* but we fail to be clear on this in the error log.
> It's confusing when we see those logs: the second log entry seems to talk about `{*}task 3.0{*}` (it's actually partition 3 and retry attempt 0), but the `{*}TID 363{*}` is already occupied by `{*}task 2.0 in stage 57.1{*}`.

> Also, it's unclear at which stage retry attempt, the lock is acquired (or fails to be acquired)
