Subject [jira] [Commented] (HADOOP-8101) Security changes for Hadoop for Windows
Date Fri, 30 Mar 2012 17:40:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13242581#comment-13242581

Aaron T. Myers commented on HADOOP-8101:

bq. I think you mean the work done in HADOOP-8121. Can that be ported to this branch if needed?
When running on Windows, I think we might be able to get away using Windows shell commands
which use the built-in OS support (taking advantage of the efficiency and caching provided
by Windows).

I was indeed referring to HADOOP-8121. Sure, providing an implementation that shells out could
make sense too, though note that Hadoop itself has built-in caching for user -> group mapping,
so it might not make that much of a difference from a performance perspective.

bq. I think, if I understand Sanjay's intent correctly, he is describing the support needed
in a non-secure (non-authenticated) Hadoop setup. Hence, the LTC etc pieces are not yet in
the picture. Sanjay, please correct me if needed.

Ah, my mistake. We might want to update the description of this JIRA to make it clear exactly
what the scope of this change is intended to be.

bq. As an aside, LTC (LinuxTaskController) is a pieces of native code that gets executed on
demand. If that abstraction is correct, it can be replicated for Windows although it might
make sense to revisit the abstraction.

Sure, makes sense.
