---------------------------------------

             Summary: Improve permgen/metaspace settings.
                 Key: IGNITE-3409
                 URL: https://issues.apache.org/jira/browse/IGNITE-3409
             Project: Ignite
          Issue Type: Task
          Components: general
    Affects Versions: 1.6
            Reporter: Vladimir Ozerov
            Priority: Critical
             Fix For: 1.7


Currently we explicitly set {{MaxPermSize}} in several places. Most notable - {{ignite.bat}} and {{ignite.sh}}.
As most users are on Java 8 now, they see annoying JVM warning on node startup:

{quote}OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0{quote}

Let update our scripts, so that {{MaxPermSize}} is used for Java 7 and {{MaxMetaspaceSize}} for Java 8 +.
