Subject [jira] Commented: (HADOOP-6925) BZip2Codec incorrectly implements read()
Date Tue, 24 Aug 2010 22:30:17 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12902112#action_12902112

Greg Roelofs commented on HADOOP-6925:

This may fix HADOOP-6852, as well.  (The unit test in question is available as a standalone
patch in MAPREDUCE-1927, which is awaiting review.)  If so, I can update the unit test to
uncomment the relevant bzip2 test.

I'll make a note to check this soon...

> HADOOP-4012 added an implementation of read() in BZip2InputStream that doesn't work correctly
when reading bytes > 0x80. This causes EOFExceptions when working with BZip2 compressed
data inside of sequence files in some datasets.
