Change subject: Add ninja support for faster incremental builds
......................................................................
Add ninja support for faster incremental builds
Ninja resolves dependencies much faster, so if only a couple of files
are changed "ninja -j ${IMPALA_BUILD_THREADS} impalad" returns within a
second or two, while make can take tens of seconds to resolve all the
dependencies.
This requires ninja to be installed. It is widely available, e.g. in the
ninja-build package on Ubuntu.
Ninja can be enabled by passing "-ninja" to buildall.sh or
make_impala.sh. The same targets should work as with make.
The default Ninja status output is fairly terse. It can be customised
with an environment variable. E.g. I have
export NINJA_STATUS="[%u to run/%r running/%f finished] "
Also fixes a bug in make_impala.sh where invalid arguments were ignored.
