user is not allowed to impersonate admin in hbase thrift server

[#1]

i am new in hbase developer, and i have a problem with my hbase.

for the first time, i can use hbase thrift server and can use hbase browser in hue very soft

but when my computer restart, and i start manually again the hbase thrift by command "hbase thrift start" in terminal. it returns "user root/myusername is not allowed to impersonate admin". 

i don't know why. i have changed all the configuration.

add "hadoop.proxyuser.hbase.hosts" and "hadoop.proxyuser.hbase.groups" with value "*"

and still don't change the error in the hue web UI.

anybody can help me ?

please i need somebody help, i can't continue my thesis.. 

thank you very much.

you might try adding the following to core-site.xml seems like the error is talking about the root group. 

hadoop.proxyuser.root.groups=*
hadoop.proxyuser.root.hosts=*

If you are running cloudera manager, you need to add those in cloudera manager itself, the config is not in the traditional space, but instead in a seperate folder managed by cloudera for each individual service. Confusingly, the config is in the traditional space is for the "gateway".
