示例1: expandGlobs
// expandGlobs recursively expands globs in a filepath. It assumes the paths
// are already cleaned and normalize (ie, absolute).
func expandGlobs(client *hdfs.Client, globbedPath string) ([]string, error) {
parts := strings.Split(globbedPath, "/")[1:]
var res []string
var splitAt int
for splitAt = range parts {
if hasGlob(parts[splitAt]) {
break
}
}
var base, glob, next, remainder string
base = "/" + path.Join(parts[:splitAt]...)
glob = parts[splitAt]
if len(parts) > splitAt+1 {
next = parts[splitAt+1]
remainder = path.Join(parts[splitAt+2:]...)
} else {
next = ""
remainder = ""
}
list, err := client.ReadDir(base)
if err != nil {
return nil, err
}
for _, fi := range list {
match, _ := path.Match(glob, fi.Name())

}示例2: RecurseInfos
func RecurseInfos(hdfsClient *hdfs.Client, hdfsDir string) ([]HadoopFile, error) {
hdfsFiles := make([]HadoopFile, 0)
dirs, err := hdfsClient.ReadDir(hdfsDir)
if err != nil {
return nil, err
}
for _, fileInfo := range dirs {
if fileInfo.IsDir() {

if err != nil {
return nil, err
}
for _, f := range recurseInfos {

}
} else {

}
}
return hdfsFiles, nil
