我有一个4节点集群（hadoop 2.5.2）（Hbase 1.0.0），主机（作为salve）和主机上有3个从机。在调用start-hbase.sh之后，jps没有显示在主服务器上运行的HRegionServer进程，但是在所有三个从服务器上都没有运行。
主服务器上的日志文件显示：

答案 0 :(得分：0)
这与HBase 1.0.x中的许多问题有关：HBASE-11575，HBASE-13453和HBASE-13479。
this comment on HBASE-13479中提到的解决方法是在hbase-site.xml中手动配置以下端口：
hbase.regionserver.port hbase.master.info.port hbase.regionserver.info.port 升级到HBase 1.1.x是另一种选择（对我有用）。
