Description

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.
