Re: [Gluster-users] gluster map/reduce performance..
Yes, I used the GlusterFS plugin. Gluster version is - 3.3 beta 2. For the Volumes Distributed-mirroring volume: Using 4 server and 2(brick)x2(replica) configuration Stripe-mirroring volume : Using 4 Server and 4(stripe count) x 2 (repica) configuration For the Map/reduce system I user 6 server ( 4 is the brick server and other 2 is for just map/reduce ) I checked your source file, but I can’t find any clue for the Performance degradation in Merging Stage. ( I think it is connected with writing) Actaully, In writing test, Gluster was quite good. So I’m little confused right now.

The latter is basically configuring Hadoop to use GlusterFS mount point (e.g. FUSE mount) as the data directory for Hadoop's DFS.

Hi, all, i try to check the performance of Map/Reduce of Gluster File system. Mapper side speed is quite good and it is sometimes faster than hadoop's map job. But in the Reduce Side job is much slower than hadoop. i analyze the result and i found the primary reason of slow speed is bad performance in Merging stage.

Re: [Gluster-users] Problem with VM images when one node goes online (self-healing) on a 2 node replication gluster for VMware datastore
Maybe the stalling time could be decreased if you set the gluster.data-self-heal-algorithm as ‘diff’ But don’t expect too much speed up.

There are betas to try out though :). Perhaps somebody else can say how stable 3.3-beta2 is compared to 3.2.4?

[Gluster-users] gluster is buildable on OSX?
I’m trying to build gluster3.3-beta2 release. But I realize that there’s one variable which is not compatible with OSX. It’s ‘_PATH_MOUNTED’ variable which stands for “/etc/mtab” I thought it’s for checking mount status. The “/etc/mtab” doesn’t exist at all. Is There any way to handle this?
