Larry McCay commented on HADOOP-12548:
--------------------------------------
[~steve_l] - thanks for the review!
1. sure
2. good question: it depends on the credential provider being used but in
general the inability to resolve a credential due to some unexpected error -
like not having permission to read a keystore or file, etc. So, if initialize
were to be called in every thread in such a circumstance there may be a lot of
noise. If it is called in every thread then it may make sense to change that
from a warn to a debug.
