Description

I recently upgraded from Fedora 22 to Fedora 25 (I'm assuming this means the latest and greatest compilers, cmake etc.) My trunk build failed with this error:

[WARNING] /home/raviprak/Code/hadoop/trunk/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-nativetask/src/main/native/src/lib/Log.h:35:67: error: unable to find string literal operator ‘operator""_fmt_’ with ‘const char [37]’, ‘long unsigned int’ arguments

This applies to any string literal followed without white space by some macro. To fix this, add some white space between the string literal and the macro name.
