To build: 1. Download and install leiningen http://github.com/technomancy/leiningen 2. $ lein deps 3. $ lein install core libs for s3, ec2, ssh. build upon the core is remote repl and cluster capabilities. in a couple cases, we use an erlang convention of the ! syntax representing "reomote" (on another process) execution. the first argument to ! in erlang is the pid, wheras in our api, it is an open ssh session or socket. there is no ! operator or fn, we just use the ! suffix convention to communicate remote execution. remote shell execution. (sh! session "tar -xzf repl.tar.gz") remote repl evaluation. eval! (eval! socket (execute (workflow some-cascading-workflow))) TODO: add examples for usages. TODO: the persistent shell session using jsch ChannelShell is shaky at best, although exec works fine. eval! may be simpler if we could use LineNumberingPushbackReader see comment in remote_repl.clj stuff to poll and pull info from hadoop tracker url into repl
