Hello all, Has anyone been in a situation where hardwares in a hadoop cluster are different when running non-Java binaries on Hadoop? e.g. a c++ map-reduce binary was compiled on a 32-bit CPU, but Hadoop cluster consists of both 32 and 64 bit machines. My guess is that the result from this situation will be a big mess.
Does Hadoop have a system or rules to prevent or help such situations? (e.g. a config system that prevents a 32 bit binary from running on a 64bit node) Also when compiling C++ map-reduce source codes with the given build.xml in version 0.14.1, does it compile in 32 bit mode? Any comments and ideas will be appreciated. Thank you in advance. Regards, Taeho -- Taeho Kang [tkang.blogspot.com]
