Log context

Log “deleted previously created; but not yet committed; next generation [{}]. This can happen due to a tragic exception when creating a new generation” classname is Translog.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 // For this to happen we must have already copied the translog.ckp file into translog-gen.ckp so we first check if that file exists
                // if not we don't even try to clean it up and wait until we fail creating it
                assert Files.exists(nextTranslogFile) == false || Files.size(nextTranslogFile)
