Allon Mureinik has submitted this change and it was merged. Change subject: webadmin: Reimplement DataCenterGuideModel#updateOptionsNonLocalFS ...................................................................... webadmin: Reimplement DataCenterGuideModel#updateOptionsNonLocalFS This patch reimplments DataCenterGuideModel#updateOptionsNonLocalFS with Java 8 streams instead of the for loop it used to iterate the hosts. Besides producing more elegant code, this reimplementation also improves performance by extracting the cluster IDs to a Set before attempting to match them to hosts. Thus, for a system with N hosts and M clusters, this operation is reduced to an O(N) operation instead of an O(M*N) operation. The Linq#isClusterItemExistInList method, which is no longer needed after this rewrite, is thus removed.
