Review comment:
I think this is good move but since so many methods of this class have
started throwing TNFE, all callers of all these methods have handled change
accordingly? Like HBaseFsck etc?

Review comment:
This could be
```
public boolean evaluate() throws IOException {
try {
return getHBaseAdmin().tableExists(tableName)
&& getHBaseAdmin().isTableEnabled(tableName);
} catch (TableNotFoundException tnfe) {
return false;
}
}
