Subject [jira] [Commented] (HDFS-4188) Add a snapshot id comparator
Date Fri, 16 Nov 2012 00:47:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4188?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13498481#comment-13498481

Aaron T. Myers commented on HDFS-4188:

Patch looks pretty good, thanks for making it.

Perhaps we should add some tests specifically for ReadOnlyList#binarySearch, since it's no
longer just delegating to a library method?

> The Snapshot class currently has two compareTo methods. The one for comparing IDs is
not implementing the Comparable interface since Java does not allow implementing the same
interface twice with different generic types.  It is better to remove one of the compareTo
methods for avoiding confusion.
