Subject HBase in a virtual cluster
Date Thu, 25 Mar 2010 15:07:57 GMT
Hi All,

Has anyone got experience in using HBase in a cluster of virtual machines (not
dedicated HW nodes)? Is that configuration reliable enough to build production
systems upon it?

As far as I understand, Java timing functions (like System.curentTimeMillis(),
Thread.sleep() etc.) work unprecisely in virtual machines, so any kind of
unsynchronization between nodes is possible.  For that reason (it’s my
understanding), the virtual clusters are generally bad idea when using HBase.
Correct me, if I’m wrong.

Any comments are appreciated.
