>
> In the Linux environment, when there are multiple concurrent add jars through
> HiveCli or JDBC, the system cpu will increase. The currently used
> FileUtil.chmod(dest, "ugo+rx", true); method is used for file authorization,
> However, in jdk7+, can use Files.setPosixFilePermissions(path, perms); for
> file authorization. The performance is seventy to eighty times that of the
> above. Why not apply this method?
