Hi! Here's a thorny issue that I'm looking at right now which I'd appreciate a broader perspective on: it seems that currently there's a subtle (but a very dangerous) difference between running any of our init.d scripts by hand -- e.g. # /etc/init.d/hadoop-hdfs-datanode start vs. running them via a service(8) command -- e.g. # service hadoop-hdfs-datanode start
It just so happens that service is guaranteed to clean the environment up, but running the scripts directly would run them in whatever environment root might have currently. IOW, if for any reason root would set a variable up that corresponds to a var from a particular /etc/default/<name> sourced by the init.d scripts -- that would affect the script execution. What do you all think -- is this a bug or a feature? Should we, somehow, make sure that a direct execution would scrub the environment the same way that a service(8) one does? Thanks, Roman. P.S. Now, it might seem to be a trivial matter of cleanliness but I've got bitten by it today and spent quite a bit of time debugging the "incorrect" behavior only to realize that it was my environment to blame.
