["Gastón Kleiman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-7212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15897516#comment-15897516 ] 

Gastón Kleiman commented on MESOS-7212:
---------------------------------------

This behaviour is documented in {{mesos.proto}} (https://github.com/apache/mesos/blob/5ac6e156390717c34586e6e19fee4bc4cb6b01d5/include/mesos/mesos.proto#L621-L626):

{noformat}
  // 2) If 'shell == false', the command will be launched by passing
  //		arguments to an executable. The 'value' specified will be
  //		treated as the filename of the executable. The 'arguments'
  //		will be treated as the arguments to the executable. This is
  //		similar to how POSIX exec families launch processes (i.e.,
  //		execlp(value, arguments(0), arguments(1), ...)).
{noformat}

The POSIX exec calls expect first argument to be the name of the exec'd file.
