Log Context

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

             assert Files.exists(nextTranslogFile) == false ||
                    Files.size(nextTranslogFile) <= TranslogHeader.headerSizeInBytes(translogUUID) :
                        "unexpected translog file: [" + nextTranslogFile + "]";
            if (Files.exists(currentCheckpointFile) // current checkpoint is already copied
                && Files.deleteIfExists(nextTranslogFile)) { // delete it and log a warning
                logger.warn("deleted previously created; but not yet committed; next generation [{}]. This can happen due to a" +
                    " tragic exception when creating a new generation"; nextTranslogFile.getFileName());
            }
            this.readers.addAll(recoverFromFiles(checkpoint));
            if (readers.isEmpty()) {
                throw new IllegalStateException("at least one reader must be recovered");
