Example 1 with ContextsConfig

use of org.apache.accumulo.start.classloader.vfs.ContextManager.ContextsConfig in project accumulo by apache.

the class ContextManagerTest method differentContexts.

@Test
public void differentContexts() throws Exception {
    ContextManager cm = new ContextManager(vfs, new ReloadingClassLoader() {

        @Override
        public ClassLoader getClassLoader() {
            return ClassLoader.getSystemClassLoader();

}
