Change subject: WIP IMPALA-9636: Don't run retried query on the blacklisted nodes ...................................................................... WIP IMPALA-9636: Don't run retried query on the blacklisted nodes When a node is blacklisted, it is only placed on the blacklist for a certain period of time. For the current implementation, it is possible that the retried query could end up running on the node that it blacklisted during its original attempt. To avoid same failure for the retried query, we should not schedule query fragments instances on the blacklisted nodes which caused the original query to fail. This patch filter out the executers from executer group for those nodes which are blacklisted during its original attempt when make schedule for the retried query. Testing: - TODO: add new test cases to cover the new code. - Passed existing retried query tests. - Passed core tests.
