Subject [jira] [Updated] (HDFS-7831) Fix the starting index of the loop in FileDiffList.findEarlierSnapshotBlocks().
Date Tue, 24 Feb 2015 08:00:38 GMT

Konstantin Shvachko updated HDFS-7831:
--------------------------------------
    Attachment: HDFS-7831-01.patch

Fixed the starting index for the loop. Also we do not need to check that {{i < diffs.size()}},
because now it always is.
This should be treated as an optimization, so there are no additional test cases.

> Currently the loop in {{FileDiffList.findEarlierSnapshotBlocks()}} starts from {{insertPoint
+ 1}}. It should start from {{insertPoint - 1}}. As noted in [Jing's comment|https://issues.apache.org/jira/browse/HDFS-7056?focusedCommentId=14333864&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14333864]
