Subject [jira] [Commented] (COMPRESS-358) Offset is larger than block size in IWA dialect of FramedSnappyCompressorInputStream
Date Mon, 09 Jan 2017 14:38:58 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15811917#comment-15811917
] 

Stefan Bodewig commented on COMPRESS-358:
-----------------------------------------

[~tallison@apache.org] while working on COMPRESS-246 I discovered a few bugs in {{SnappyCompressorInputStream}}
where it was losing data when sliding the window too early or incorrectly counting bytes read
when the window needed to slide. Could you give the current master branch a try to see whether
it solves your problem?

.iwa files.  I got the following on two files:
