Hregionserver启动之后马上死了的问题

ERROR [main] regionserver.HRegionServerCommandLine: Region server exiting
java.lang.RuntimeException: HRegionServer Aborted
        at org.apache.hadoop.hbase.regionserver.HRegionServerCommandLine.start(HRegionServerCommandLine.java:66)
        at org.apache.hadoop.hbase.regionserver.HRegionServerCommandLine.run(HRegionServerCommandLine.java:85)

        at org.apache.hadoop.hbase.regionserver.HRegionServer.main(HRegionServer.java:2400)

请问这是为什么？？

看一下权限是否足够，这里面权限包括：一些配置文件中的所配置的路径，缓存文件的路径。还有这些路径文件是否都建立了。
可以对照下面文档：

hbase 0.96整合到hadoop2.2三个节点全分布式安装高可靠文档

搞定了，往表里设置协处理器的时候抛出异常，导致HRegionServer启动后又终止了。

请问楼主，怎么解决往表里设置协处理器时抛出异常这个问题呢？

你的出异常了？可以贴出来看看

我是将Phoenix 4.0.0升级到Phoenix4.2.2时遇到这个问题的。升级后，不仅不能使用Phoenix，连HBase都不能正常运行了，启动之后不到1分钟，所有的regionserver就挂掉了。

应该是升级失败了，在server ubuntu02 上找不到这个类

这个是从官网上下的包啊，不是在线更新的，我刚才又把Phoenix版本降回4.0.0了，用这个版本的时候就不存在这个问题

确保hbase与Phoenix版本对应

嗯，版本是对应的，HBase 0.98.1+对应 Phoenix 4.x，我的是HBase 0.98.6.1 和Phoenix 4.2.2
