hbase报错org.apache.hadoop.ipc.RemoteException(java.lang.NullPointerException): java.lang.NullPointerException

这个错误找了好长时间,日志看半天,找度娘没什么用,再看stackoverflow,上面有几篇相关的帖子,但是没人回答。

看半天,没有cause,只好到idea中去看sortLocalSorts源码,结果才知道是dns解析相关的配置,查了几个主机上的hbase-site.xml没问题,HA配置也没问题,最后才知道是s201机架感知忘了配,就是这个:net.topology.node.switch.mapping.impl

具体怎么配置机架感知自己去搜博客哈,本人前几篇有关于机架感知的博客,怎么配置可以自己去看。然后还有一个问题,就是要将集群时间进行统一,具体自己去搜:hbase集群时间统一。然后手动启动hmaster和hregionserver

用java运行Hadoop程序报错:org.apache.hadoop.fs.LocalFileSystem cannot be cast to org.apache.

用java运行Hadoop例程报错:org.apache.hadoop.fs.LocalFileSystem cannot be cast to org.apache.所写代码如下: package com.pcitc.hadoop; import java.io.IOException; import org.apache.hadoop.conf.Configuration; import org.apache.hadoop.fs.FileSystem; import org.apache.h

org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException)

在运行hadoop的程序时,向hdfs中写文件时候,抛出异常信息如下: Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Permission denied: user=Administrator, access=WRITE, inode="/user":root:supergroup:drwxr-xr-x 原因:Hdfs中的/user

Eclipse连接HBase 报错:org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

在eclipse中连接到HBase报错org.apache.hadoop.hbase.PleaseHoldException: Master is initializing,搜索了好久,网上其它人说的解决办法对我都没用: - 做时间同步 - hbase-site.xml中参数hbase.rootdir使用hdfs协议 - 关闭防火墙 最终,参考这个论坛帖子:http://www.aboutyun.com/thread-20600-1-1.html(Hbase shell 启动报错,使用statu

Hadoop HA HDFS启动错误之org.apache.hadoop.ipc.Client: Retrying connect to server问题解决

近日,在搭建Hadoop HA QJM集群的时候,出现一个问题,如本文标题. 网上有很多HA的博文,其实比较好的博文就是官方文档,讲的已经非常详细.所以,HA的搭建这里不再赘述. 本文就想给出一篇org.apache.hadoop.ipc.Client: Retrying connect to server错误的解决的方法. 因为在搜索引擎中输入了错误问题,没有找到一篇解决问题的.这里写一篇备忘,也可以给出现同样问题的朋友一个提示. 一.问题描述 HA按照规划配置好,启动后,NameNode不能
