> In our production environment, we always get some certain exceptions from Hadoop or HBase, like "org.apache.kylin.job.exception.NoEnoughReplicationException", "java.util.ConcurrentModificationException", which results in job failure. While, these exceptions can be handled by retry actually. So, it will be much more convenient if we are able to make job retry on some configurable exceptions.
