请问这是怎么回事？ 难道这个版本没有-ROOT-表？

该版本的.META.表也命名为hbase：mete
hbase(main):002:0> scan '.META.'

ERROR: .META. no longer exists. The table has been renamed to hbase:meta

Here is some help for this command:
Scan a table; pass table name and optionally a dictionary of scanner
specifications. Scanner specifications may include one or more of:
TIMERANGE, FILTER, LIMIT, STARTROW, STOPROW, TIMESTAMP, MAXLENGTH,


有知道的大神吗？求解答，多谢！

因为后面HBase引入了namespace的概念，表命名空间隔离了。所以原来的-ROOT-表的功能由hbase:meta和hbase:namespace两张表完成
