Subject [jira] [Updated] (YARN-4951) large IP ranges require the creation of multiple reverse lookup zones
Date Tue, 12 Apr 2016 19:56:25 GMT

     [ https://issues.apache.org/jira/browse/YARN-4951?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Maron updated YARN-4951:
---------------------------------
    Attachment: 0001-YARN-4757-address-multiple-reverse-lookup-zones-and-.patch

An approach that:

1)  Add config properties for netmask, IP range min, and IP range max
2)  Uses SubnetUtils to find the list addresses based on subnet and mask, selects the network
addresses (end in ".0") for resulting list, and allows for the addresses to be filtered based
on range values.

> Large subnet definitions (e.g. specifying a mask value of 255.255.224.0) yield a large
number of potential network addresses, each requiring a separate reverse zone definition (given
that reverse zones include the first 3 IP bytes in reverse order).
