HADOOP报错Incompatible namespaceIDs
今早一来，突然发现使用-put命令往HDFS里传数据传不上去了，抱一大堆错误，然后我使用bin/hadoop dfsadmin -report查看系统状态

Download a cacert.pem for RailsInstaller

Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)
