Edward Nevill updated HADOOP-11484:
-----------------------------------
Description:
Hadoop fails to build on ARM aarch64 (or any non x86 platform) because of the
following in
hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-nativetask/src/main/native/src/lib/primitives.h
{noformat}
/**
* little-endian to big-endian or vice versa
*/
inline uint32_t bswap(uint32_t val) {
__asm__("bswap %0" : "=r" (val) : "0" (val));
return val;
}
inline uint64_t bswap64(uint64_t val) {
#ifdef __X64
__asm__("bswapq %0" : "=r" (val) : "0" (val));
#else
uint64_t lower = val & 0xffffffffU;
uint32_t higher = (val >> 32) & 0xffffffffU;
lower = bswap(lower);
higher = bswap(higher);
return (lower << 32) + higher;
#endif
return val;
}
