hbase.rootdir 参数写成了 hbase.root.dir
hbase-site.xml如下：
- <configuration>
- <property>
- <name><span style="color: rgb(255, 0, 0);">hbase.root.dirspan>name>
- <value>hdfs://master:9000/hbasevalue>

- <value>master,slave1,slave2value>

hbase.root.dir
hdfs://master:9000/hbase
hbase.cluster.distributed
true
hbase.master
hdfs://master:6000
hbase.zookeeper.quorum
master,slave1,slave2
修改hbase-site.xml后，重启集群，一切恢复正常。
