@yashmayya Right now I'll have every controller run the check on each tenant rebalance job, but only one controller can get to retry that job if stuck. This is done by compare and swap using `ControllerZkHelixUtils::addControllerJobToZK`. For example if two controllers both detect `jobID_123` is stuck and want to retry it, only the one who creates the job ZK metadata for `jobID_123_2`(the job ID with the new attempt ID) will actually retry the job. https://github.com/apache/pinot/blob/d01cb710100b8601574bd92d73c1c16092ece01e/pinot-controller/src/main/java/org/apache/pinot/controller/helix/core/rebalance/tenant/TenantRebalanceChecker.java#L191-L193 -- This is an automated message from the Apache Git Service.
