elasticsearch安装插件：无法为对象堆保留足够的空间

Question

I am trying to install the elasticsearch plugin with the command: ./plugin install license which I found on this tut: link

But I get the error message:

Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

After that even if I run java -version I get the same error! Before I run ./plugin install license java -version worked fine and printed:

java version "1.7.0_79" OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1) OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

Does anybody know whats my problem here? Its a fresh install of Ubuntu 14.04.4 LTS and I installed elasticsearch 2.2.3
