Date Sun, 11 Aug 2013 18:11:47 GMT
Yu Li created HADOOP-9863:
-----------------------------

             Summary: Snappy compression cannot work on Big-Endian 64 bit platform w/o backporting
HADOOP-8686
                 Key: HADOOP-9863
                 URL: https://issues.apache.org/jira/browse/HADOOP-9863
             Project: Hadoop Common
          Issue Type: Bug
          Components: native
    Affects Versions: 1.2.1, 1.1.2, 1.1.1
            Reporter: Yu Li
            Assignee: Yu Li


w/o changes made in HADOOP-8686 on SnappyCompressor.c, snappy compression in branch-1 hadoop
on big endian 64 bit platform (ppc64 for example) will generate incorrect .snappy (almost-empty)
file because of type casting from size_t to jint. Will include more detailed analysis in comments.
