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。

Bengaluru IoT Roadshow highlights

We had an Intel IoT roadshow at Bengaluru on 11th and 12th of April 2015 at MLR Convention center, Whitefield. We got an overwhelming response from IoT enthusiast to participate in this event. Finally, we manage to accommodate 150 participants. 

We had people from different background and experience level in this roadshow. We had students, software/app developers, hardware developers, hobbyist and makers. Everyone got in there with their innovative idea in mind and they were eagerly waiting to implement it using Intel Edison.

haxm installation failure in win7 64

Hi All,
I am writing this post to ask for help about installing the intel haxm, I previously used win8, and I could install the haxm without any problems, but a few
days ago, I change the os to win7 64bit, while I cannot install the haxm after I tried many ways to fix it.
I refered to the the page : https://software.intel.com/en-us/blogs/2014/03/14/troubleshooting-intel-...
and tried the ways that mentioned in the page, but nothing helped. I went to bios and enabled the VT.

below are the info captured about my pc.

hoping to get any helpful info from you guys, many thanks.

Question about the HAXM driver

I want to apply the HAXM on the QEMU for my x86 virtual machine.
The QEMU for the Tizen and the Android is the open source.
So, I am analyzing and referencing them.
But, the Android's QEMU is very old version.
So, my custom QEMU is based on the Tizen's QEMU.

Recently, I checked the issue related with HAXM version.
The Tizen QEMU use the HAXM 1.0.5, and the Android QEMU use the HAXM 1.1.1.
The Tizen QEMU cannot run and close the emulator on the HAXM 1.1.1.
It can run and close on the HAXM 1.0.5.
