Kengo Seki commented on HADOOP-11406: ------------------------------------- Thanks [~aw], it sounds better. I'll do as follows: - in hadoop-functions.sh, move the for loop into another function as the default. - put the paralell xargs one into hadoop-user-functions.sh.example as a example to override above. > xargs -P is not portable > ------------------------ > > Key: HADOOP-11406 > URL: https://issues.apache.org/jira/browse/HADOOP-11406 > Project: Hadoop Common > Issue Type: Bug > Components: scripts > Affects Versions: 3.0.0 > Environment: Solaris > Illumos > AIX > ... likely others > Reporter: Allen Wittenauer > Assignee: Kengo Seki > Priority: Critical > Attachments: HADOOP-11406.001.patch > > > hadoop-functions.sh uses xargs -P in the ssh handler. -P is a GNU extension > and is not available on all operating systems.
