1.解决安装好大数据组件后，jps出现的进程process information unavailable，jps如下
[email protected] ~]# jps
14656 Main
29344 – process information unavailable
29362 – process information unavailable
29347 – process information unavailable
29350 – process information unavailable
29355 – process information unavailable
32622 Jps
2.主要原因是/tmp/hsperfdata_root目录下为空，需要把其它以hsperfdata打头的目录下的文件copy到hsperfdata_root下，jps显示正常
- cd /tmp
- ll /tmp
3.将hsperfdata_cloudera-scm/下的进程文件copy到hsperfdata_root目录下
4.jps查看，进程正常
