load balanced nodes accepting jobs before ready

When loadbalancer adds nodes, itís making them available to the scheduler before theyíre fully provisioned. Iím using pkginstaller plugin to install required libraries across the cluster, but if a job hits a newly added node before pkginstaller has finished, those jobs then fail because the library was not yet installed.

So, I need to either

  1. force loadbalancer to wait until all provisioning is complete before readying the node for job scheduling
  2. Bypass pkginstaller altogether by making the master node share its libraries with the rest of the cluster over nfs

Any suggestions?
