hello there, im trying to compile libhdfs in order but there are some
problems. According to http://wiki.apache.org/hadoop/MountableHDFS i have
already installes fuse. With ant compile-c++-libhdfs -Dlibhdfs=1 the buils is
successful.
However when i try ant package -Djava5.home=... -Dforrest.home=... the build
fails and the output is the below :
[exec]
