James Clampffer commented on HDFS-9340:
---------------------------------------
+1 on the patch, but I think a jira that wires up make test to maven is high
priority. If you could implement or help with that step I think I could go the
rest of the way with the integration tests with minimal support.
"Does the current pom.xml run "make"? I don't see anything in the pom that is
compiling libhdfspp."
To answer your question Bob it is running make, but how that gets invoked I
have no idea. I just looked for the static libraries after the build and they
all showed up.
"Can you be more concrete on what kinds of documentation can help here? It will
be great to capture your experience in the wiki for other contributors."
Bob's question about make is pretty much the same thing I'm running into. I
know that the build primarily uses maven but things start getting hard to
follow when that calls ant which calls cmake; at least that's my current
understanding of the chain of events to build libhdfs++. In my experience as a
new contributor it's fairly difficult to follow how mvn install <some flags>
eventually invokes cmake, and even what the working directories for this
process are.
I guess what I'd like is a page that says something like:
1a) here's the pom.xml at the root of the project, and a brief summary what the
most important bits of it do
1b) here are the options you can give at that level to control the build and
change what sorts of tests get run with different flags etc
2a) when you're using a language like C++ that isn't natural for maven these
are the steps that are taken to invoke something like cmake
2b) here are some references to the plugins that do most of the work
2c) here's a snippet of code that you could drop in a pom.xml to build some C++
project, or here's a a project that should be considered a prototypical example
As someone with a C and C++ and hardware background I don't have the high level
of familiarity with maven, ant, and the rest of the java ecosystem that I think
many Hadoop contributors take for granted. I think the steps above would go a
long way towards enabling people with with experience similar to mine to become
productive quickly. If there isn't much of anything in this area I'd be happy
to contribute to a wiki that addresses this, I just have to learn it all first.
