FLAGS_enable_multi_tenancy) {
use GTEST_SKIP() instead?

How about:

 Fail to rewrite the instance metadata for path: $0, now try to rollback all 
the instance metadata file.

PS12, Line 684:   metadata->clear_format_stamp();
Is it necessary to clear it? The next line will write over it.


http://gerrit.cloudera.org:8080/#/c/19622/12/src/kudu/fs/fs_manager.cc@832
PS12, Line 832: // If '--encrypt_data_at_rest' is not enabled or the tenant 
information is specified,
              :   // we will not add the tenant information to the metadata, 
even the default tenant.
The comment is a bit of confused. 1. it just explain the "tenant information", 
but the following codes are related both to "tenant information" and "server 
key" 2. the flag "--encrypt_data_at_rest" is far away to the real invoker 
(after line 894?)

As all the if-else statements have their own comments, I suggest to remove this 
comment.
