构建命令：
tar zcvf GPLEXTRAS-5.0.0-gplextras5b2.p0.32-el6.parcel GPLEXTRAS-5.0.0-gplextras5b2.p0.32/ --owner=root --group=root
把文件都放到一个http可访问的目录下，然后在“Parcel 设置”里面配置URL 目录结构
-rw-r--r-- 1 kpi kpi 15509175 Jul 19 15:34 CUSTOM-5.4.0-1.cdh5.4.0.p2.5-el6.parcel
-rw-rw-r-- 1 kpi kpi 41 Jul 19 15:41 CUSTOM-5.4.0-1.cdh5.4.0.p2.5-el6.parcel.sha1
-rw-r--r-- 1 kpi kpi 500 Jul 19 15:52 manifest.json
manifest.json 文件如下，里面的hash值要对应上，components里面随便填，不要和原来的冲突
