(Updated Sept. 14, 2014, 4:05 p.m.) Review request for mesos, Adam B, Benjamin Hindman, Bernd Mathiske, and Vinod Kone. Changes ------- Added return value check for pipe2 Added #include <unistd.h> Bugs: MESOS-1792 https://issues.apache.org/jira/browse/MESOS-1792 Repository: mesos-git Description ------- Adds an overload of os::shell that allows to run a command with stdin and/or stdout substituted by file descriptors passed as parameters. This will allow to pipe a stream of data in and out of a process e.g. directly from download to extraction, as proposed by Bernd Mathiske in MESOS-1667. A unit test has been added.
