Change subject: IMPALA-6067: Enable s3 access via IAM roles for EC2 VMs

Patch Set 3: Code-Review+1


I'm fine with this as-is; there are very minor nits that you can tackle if you'd like. Please
do answer the question about changing the FE tests to just use s3a so that we can remove the
hackery altogether.

File bin/
PS3, Line 56:   exit 0;
you don't need the semicolon
File testdata/cluster/admin:
PS3, Line 289:         sed '/<!-- BEGIN s3a security settings/,/END s3a security settings
-->/d' \
You could use "sed -i" to edit this in place, though I know Mac OS X sed behaves slightly
differently than Linux sed, causing some trouble. We seem to have some limited "sed -i" usage

I'm not insisting.
File testdata/cluster/node_templates/common/etc/hadoop/conf/core-site.xml.tmpl:
PS3, Line 59:   <!-- Fake s3n credentials required for FE tests -->
Is there any reason not to s/s3a/s3n/ in the tests so that we can get rid of this?
