At some point a while back I added retry support for when jobs fails. You provide a RetryPolicy that determines if and when a job should be retried. This was primarily intended for non-repeating, single-execution jobs. For repeating jobs, i.e., the compression job, the job is supposed to be executed according to its trigger. Suppose the compression job is scheduled to run at 15:00 and repeats every two hours. If the 15:00 execution fails, the scheduler is supposed to retry the job (for all intensive purposes) immediately with the same trigger time of 15:00. When the job completes normally, its trigger will get updated in the database to the next execution time of 17:00. If it already later than 17:00, then the scheduler will again execute the job right away. There was a bug with the error handling such that the job wasn't getting retried for the 15:00 execution. The trigger was getting advanced and set to 17:00. The temp table being compressed gets dropped at the end of the compression job. Unless the failure was dropping the table, we end up with orphaned temp tables any time the job fails. This commit does away with the RetryPolicy since it is not used. This means that when a job fails, regardless of whether or not it is repeating, it will be retried with the same trigger until it completes normally. * [HWKMETRICS-763] add "local" job to check for expired temp tables Due to the bug in SchedulerImpl.java which was fixed in my previous commit, there are openshift clusters with literally hundreds of expired temp tables. They are expired in the sense that they are older than the data retention and therefore do not contain any live data. This commit adds a "local" job that checks for and drops expired tables. The job is local in the sense that it is local to the hawkular-metrics server. It is not run via the job scheduler. * [HWKMETRICS-763] use Observable.empty to get rid of filter call Commit: 7afe1aea1c1b046e4e5dafa5c015491a6968025f https://github.com/hawkular/hawkular-metrics/commit/7afe1aea1c1b046e4e5da...
