java - 在主节点 : Failed construction of Regionserver : java.net.BindException

Question

我有一个 4 节点集群(hadoop 2.5.2)(Hbase 1.0.0)，主机上有一个主节点(作为从节点)和 3 个从节点。调用 start-hbase.sh 后，jps 没有显示 HRegionServer 进程在 master 上运行，但在所有三个 slave 上运行正常。

master 上的日志文件显示:

Answer 1

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 中提到的解决方法就是在hbase-site.xml中手动配置如下端口:

• 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)。
