目前可供儲存虛擬化的解決方案有 Ceph, Lustre, GPFS (IBM 有放 GPL 版本)
不過個人建議應該要考慮 replication 支援以及 deduplication 支援。
目前支援 deduplication 的檔案系統有 (1) ZFS (2) lessfs (3) SDFS

由於 Hadoop 本身架構屬於 Share Nothing 架構,因此不方便作參數傳遞,
一直覺得有機會的話,可以結合 Apache ActiveMQ 來改善 Hadoop 一些即時性的問題。

除了虛擬化以外,目前多數在談像是 BI 或者一些大型數據的分析。

Rex 想問的是 Graph 演算法 ( Distributed Graph Algorithms ) ??

X-RIME 這個專案有使用 Hadoop 作 Social Network 分析,應該有用到 Graph 演算法,
不妨參考看看。

Don't use AMQ, it is way too over promoted/rated. My team had use it
in production for quite a while, and got bitten very badly.
We've done a comprehensive evaluation on AMQ, Open MQ and a couple of
proprietary MQs. In the evaluation (and also in our production
environment), we peered a number of brokers (of the same MQ,
obviously) for the purpose of HA. AMQ failed miserably, In particular,
scenarios involving stress or errors (i.e., pulling the network cable
and etc.). It fails so bad that you won't believe it is from Apache at
first.
One thing worth highlighting, the evaluation was performed by a team
who had been operating AMQ in production for more than 6 months. They
may not be the most knowledge people out there regarding AMQ, but they
sure know a thing or two.
AMQ MAY work, if you don't need HA (peering MQs into a cluster).
I am particular intrigued by the quality of its source code. (I've
blogged about its C++ client library in the past
http://fsfoundry.org/codefreak/2009/03/08/code-review-activemq-cpp/).
I've witnessed a committer checked in a fix for a CRITICAL bug that
exists in a major release with no commit log, no matter how you look
at it, it is BAD.
Flee, people. Get the hell away from AMQ.

I used the term "AMQ" as a shorthand for ActiveMQ (an implementation),
but not AMQP (a specification).

RedHat don't service MGR in Asia, we tried.

我沒用過,但據說用 C++ 開發的 Sector/Sphere 比 Hadoop 快不少。
