[GitHub] [hadoop] GauthamBanasandra opened a new pull request, #4145: HDFS-16473. Make HDFS stat tool cross platform

GauthamBanasandra opened a new pull request, #4145:
URL: https://github.com/apache/hadoop/pull/4145

### Description of PR
The source files for `hdfs_stat` uses `getopt` for parsing the command line arguments. getopt is available only on Linux and thus, isn't cross platform. We need to replace getopt with `boost::program_options` to make this tool cross platform.

### How was this patch tested?

# hdfs_stat
This tool was testing locally with the Hadoop cluster setup in pseudo-distributed mode.
I ran the tool by providing the path to a file as the argument.

```bash
$ ./hdfs_stat ~/some-dir/some-data.txt
```

I verified the output against the information displayed in the UI.

I then ran the tool by providing the path to a directory as the argument.

```bash
$ ./hdfs_stat ~/some-dir
```

I then ran the tool by providing a non-existent path as the argument.

```bash
$ ./hdfs_stat ~/some-non-existent-path
```
