Hadoop Hbase 升级

Hadoop HDFS 与Hbase升级笔记

由于之前使用了hadoop1.0.2,hbase 使用的是hbase-0.92.1 但是一次事故导致元数据丢失,且修复元数据的类本身有BUG
所以摆在眼前的只有两条路:
1、修改hbase源码重新编译 hbase 修复BUG
2、升级到下一个版本,且这个版本已经修复了此BUG 从release node中看到 0.92.2及以后版本均修复了此bug
  所以决定升级到最新的稳定版 hbase-0.94.3 而此版本的hbase 和hadoop-1.0.4 的兼容性最好,所以hadoop 连带升级到hadoop-1.0.4

1. Hadoop升级步骤:
 (1)停止集群上的所有MR任务,包括Hbase(如果Hbase在使用中,先停掉,接着是zookeeper)
 (2)停止DFS(1、2两步也可以在hbase和zookeeper关闭后使用stop-all.sh脚本直接关闭)
 (3)删除临时数据,即在core-site.xml中设置的hadoop.tmp.dir的value所文件目录下的文件
 (4)备份HDFS元数据

java socket 多线程网络传输多个文件

     由于需要研究了下用 java socket 传输文件,由于需要传输多个文件,因此,采用了多线程设计。客户端每个线程创建一个 socket 连接,每个 socket 连接负责传输一个文件,服务端的ServerSocket每次 accept 一个 socket 连接,创建一个线程用于接收客户端传来的文件。

SOFTWARE ENGINEER NEEDED

This probably is not the right place to post this, but whatever. I have run out of places to turn to find a software engineer, for an interview i need to conduct for an engineering course at my school. If anybody here is willing to take a few minutes out of your day to help me, it would be much appreciated 

HAXM installation failed !

 

I'm trying to install Intel HAXM . However, during installation, I get an error saying that VT-x is not enabled.

The Intel VT-x is supported by my computer’s processor and I go into system BIOS and find VT-x enabled !!

I don't know what is the problem?!! Why this error occurs ?

My OS is windows 8.

Thank you..
