> Reproduction Steps:
> 1. We create a new table with many regions , for example:
> {code:java}
> //代码占位符
> create 't01' , 'info' , SPLITS => Array(1..999).map{|e|e.to_s}{code}
> 2. At the same time, we scan meta entries of this table on meta browser by
> hbase UI
> 3. We would get NPE if those regions is initializing and the server or target
> server is null
