Subject [jira] [Commented] (ACCUMULO-3890) Use of CredentialProvider results in a lot of NN ops
Date Mon, 08 Jun 2015 20:25:01 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14577774#comment-14577774

Christopher Tubbs commented on ACCUMULO-3890:
---------------------------------------------

I'd be more comfortable pulling it back to 1.6 if the status of this was "Patch Available"
or, at the very least, "In Progress". I don't want to hold off 1.6.3 for issues not being
worked on.

> Every time we access a sensitive property or iterate over a configuration when there
is a CredentialProvider configured, it results in NN operations (as evidenced by FSNamesystem.audit
logs).  I think that we could assume the CredentialProvider is static, read its properties
once and cache them in memory to avoid these unnecessary reads.
