Joep Rottinghuis commented on MAPREDUCE-2901:
---------------------------------------------
On my Ubuntu desktop (11.04) protobuf-compiler package (2.3.0-4ubuntu2) is
installed and protoc is on the command line.
I still get the error.
http://wiki.apache.org/hadoop/DevelopingOnTrunkAfter279Merge advices to add
non-standard installation directory to LD_LIBRARY_PATH.
However, the libprotoc6 package has already put libprotoc.so.6 and
libprotoc.so.6.0.0 in /usr/lib/. Seems like a standard path to me.
It seems to me that simply checking whether protoc is in the path will not be
sufficient.
> Build should fail sanely if protoc isn't on PATH
