[jira] [Commented] (SLIDER-261) Improvements to port allocation support

["Sumit Mohanty (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLIDER-261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14116512#comment-14116512 ] 

Sumit Mohanty commented on SLIDER-261:
--------------------------------------

Slider does not have a global view of all apps deployed. The capability that can be added here is to have Slider allocate ports from within a range of ports such as 40000-40100 for an instance.

> Applications like Storm require dynamic port allocation. However, the allocated port may not get immediately used - e.g. till a Topology is deployed. In general, there is always a small window between Slider allocating a port and the application actually using it. 
> The ideal solution is some form of port reservation system that is OS backed. But in absence of such a capability Slider should ensure that allocated port is reserved for the application instance till the application is active independent of whether the application actually uses it.
