yes, the flex does this, it lets you change the size of every role in the cluster.
if you do it while the cluster is down, the changes will be picked up when you start/thaw it. If running, the changes get saved to hdfs and then the Slider AM is told to reread the settings and move to the new cluster size. If you expand the cluster, more containers are asked for. if you shrink it, then some will be picked (randomly) for release. Their location will be recorded so that if you expand the cluster again, it will request for them back -the same way it does when restarting a previously stopped cluster On 2 July 2014 15:39, Rui Zhang <[email protected]> wrote: > Hi, > > Is there a way to change the size of an application cluster in Slider?
