Eric Yang commented on HADOOP-9863:
-----------------------------------

JINT_MAX assumes a fixed size for 64bit signed integer. This may not always be 
the case for other platforms.  It would be good to use:

#include <limits.h>, and check with INT_MAX instead.

                
> Snappy compression in branch1 cannot work on Big-Endian 64 bit platform w/o 
> backporting HADOOP-8686

> 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.
