hi, i have have hadoop v2.3.0 installed on CentOS 6.5 64-bit. OpenJDK 64-bit v1.7 is my java version.
when i attempt to start hadoop, i keep seeing this message below. OpenJDK 64-Bit Server VM warning: You have loaded library /usr/local/hadoop-2.3.0/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now. It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'. i followed the instruction. here were my steps. 1. sudo yum install -y prelink 2. execstack -c /usr/local/hadoop-2.3.0/lib/native/libhadoop.so.1.0.0 however, this message still keeps popping up. i did some more search on the internet, and one user says that basically, libhadoop.so.1.0.0 is 32-bit, and to get rid of this message, i will need to recompile this into 64-bit. is that correct? is there not a 64-bit version of libhadoop.so.1.0.0 available for download? thanks,
