I don't think these ENV settings should affect the launcher ENV, these ENV settings are exclusively for the SHELL it will be executed by the launcher. If the user wants to alter the launcher ENV for some reason, they always can do it with the oozie.launcher.mapred.child.env, but by definition, anything that is oozie.launcher.* is not propagated to the action itself. > On 2011-12-05 18:40:43, Alejandro Abdelnur wrote: > > http://svn.apache.org/repos/asf/incubator/oozie/trunk/core/src/main/java/org/apache/oozie/action/hadoop/ShellActionExecutor.java, > > line 106 > > <https://reviews.apache.org/r/3000/diff/2/?file=61826#file61826line106> > > > > as the shellmain is forking a new process, these changes are not > > required for the launcher mapper process, but for the process the shellmain > > launches. > > Mohammad Islam wrote: > I think we need it here.

I thought both are same. ProcessBuilder has some functionality that makes easier to deal with subprocesses, see prev comment on setting directory. > On 2011-12-05 18:40:43, Alejandro Abdelnur wrote: > > http://svn.apache.org/repos/asf/incubator/oozie/trunk/core/src/main/java/org/apache/oozie/action/hadoop/ShellMain.java, > > line 132 > > <https://reviews.apache.org/r/3000/diff/2/?file=61827#file61827line132> > > > > consuming the stdout/stderr of the forked process must be done in > > different threads, else you may be be blocking processing/overflowing > > buffers. > > > > > > Mohammad Islam wrote: > Are you asking to spawn a new Thread to do it? actually, 2 new threads, one to consume STDOUT and other STDERR, they should be daemon threads and exit the loop on -1 read as well. both outputs should be redirected to to the launcher process STDOUT/STDERR (as then they end up in the launcher logs). the STDOUT should also be captured (a la tee) so it can be used for <capture-output> functionality. > On 2011-12-05 18:40:43, Alejandro Abdelnur wrote: > > http://svn.apache.org/repos/asf/incubator/oozie/trunk/core/src/main/resources/oozie-default.xml, > > line 1052 > > <https://reviews.apache.org/r/3000/diff/2/?file=61828#file61828line1052> > > > > this should go in the wf.schemas property, no there. > > Mohammad Islam wrote: > ok. by bad, this is not there.
