my ubuntu there are two accounts, one is an ordinary user, one is to install hadoop recently created user.
The problem now is that I run in the general account eclipse no problem at all, but in the hadoop account run on the error.
I follow this blog installed hadoop: http://www.cnblogs.com/tippoint/archive/2012/10/23/2735532.html
error display:

I was told to use xhost + ordinary users to try, results are shown below:
hadoop @ city-ubuntu :/ home / city $ xhost + city
No protocol specified
No protocol specified
xhost: unable to open display ": 0.0"
seek expert advice, be grateful
PS: Currently I use xhost + localhost, and then in the general account under ssh-X hadoop @ localhost eclipse eclipse can run, but I installed hadoop plugin did not play a role. Under ordinary users can see mapreduce options that are now under the hadoop do not see, and has the authority to plug 777.

that we should pay attention when installing Eclipse! I was also so your eclipse I do not know where you installed, I suggest you reinstall it. This must be reasonable when installed in / home under construction in an eclipse folder, and then manually install themselves on this below, if you will be free to install a bunch of questions, time for you to solve these problems not as heavy equipment. I guess you might be installed in an ordinary user's directory, but the user is not authorized to access hadoop you that the user's home directory. You have installed in / home bottom, so that all users can use eclipse, every time I use are cd / home + sudo. / Eclipse / eclipse. You look at is not the case.

your approach really solved my previous problem, but now there is a new problem!
After installing the plug-in, is not displayed on the left sidebar DFD Locations, other touches everything is normal.

I could not confirm whether the eclipse platform I run hadoop program
