> But in general, the edits file we parse does not involve all the operation
> codes. If all the operation codes are output, it is unfriendly for the
> cluster administrator to view the output.
> we usually only care about what opcodes appear in the edits file.We can
> output the opcodes that appeared in the edits file and sort them.
> For example, we can execute the following command：
> {quote} hdfs oev -p stats -i edits_0000000000000001321-0000000000000001344
> -sort -o edits.stats -v
