typo in line 459 of the Scheduler.java

LOG.error("Unexpteced failure while while updating heartbeat for execution {}.", e, ex);

Unexpteced -> Unexpected

[Subham5778]

} catch (Throwable ex) { // catch-all to avoid scheduler crash
LOG.error("Unexpected failure while updating heartbeat for execution {}.", currentlyExecuting, ex);
schedulerListeners.onSchedulerEvent(SchedulerEventType.FAILED_HEARTBEAT);
schedulerListeners.onSchedulerEvent(SchedulerEventType.UNEXPECTED_ERROR);
schedulerListeners.onExecutionFailedHeartbeat(currentlyExecuting);
}
Replaced e with currentlyExecuting for clarity in logs.
