Wei-Chiu Chuang commented on HADOOP-12581:
------------------------------------------
Thanks for the quick clarification :)
I only asked this because I did notice the id command behaves slightly
differently* on Mac than Linux (well, Mac is not POSIX-compliant anyway). So
there are corner cases unspecified that differ between systems.
* If a user has multiple groups and some of the groups numerical id can not be
resolved to group names, Linux's id returns error code 1, while Mac's id
returns error code 0 (See HADOOP-12468

> ShellBasedIdMapping needs suport for Solaris
> --------------------------------------------
>
> Key: HADOOP-12581
> URL: https://issues.apache.org/jira/browse/HADOOP-12581
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: security
> Affects Versions: 2.7.1
> Environment: Solaris
> Reporter: Alan Burlison
> Assignee: Alan Burlison
>
> ShellBasedIdMapping only supports Linux and OSX, support for Solaris needs
> adding.
> From looking at the Linux support in ShellBasedIdMapping, the same sequences
> of shell commands should work for Solaris as well so all that's probably
> needed is to change the implementation of checkSupportedPlatform() to treat
> Linux and Solaris the same way, plus possibly some renaming of other methods
> to make it more obvious they are not Linux-only.
