Description

When master is initializing, if root server died between assign root and assign meta, master will block at
HMaster#assignRootAndMeta:

assignmentManager.assignMeta();
this.catalogTracker.waitForMeta();

because ServerShutdownHandler is disabled,

So we should enable ServerShutdownHandler after called assignmentManager.assignMeta();
