NoSuchMethodError ConcurrentHashMap.keySet

[a414930249]

I encounter an error when starting the opentsdb

the error message:
Exception in thread "main" java.lang.NoSuchMethodError: java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;

it seems that the compile java version is java 8, but my jdk version is 1.7.0_80.
Is there any solution can solve this problem without changing the version of my jdk?

You may need to recompile asynchbase with 1.7 or try another version of AsyncHBase which I should have fixed and compiled with 1.7
