META不变的,只不过root信息存储在了zookeeper里面,而不需要在通过zookeeper,去查找root。这样减少了一步,自然性能提高了。
meta-region-server, backup-masters, table, draining, region-in-transition, table-lock, running, master, namespace, hbaseid, online-snapshot, replication, splitWAL, recovering-regions, rs, flush-table-proc
如上面meta-region-server便是代替了root.如下图
