Billie Rinaldi updated ACCUMULO-3890: ------------------------------------- Fix Version/s: 1.6.3 > Use of CredentialProvider results in a lot of NN ops > ---------------------------------------------------- > > Key: ACCUMULO-3890 > URL: https://issues.apache.org/jira/browse/ACCUMULO-3890 > Project: Accumulo > Issue Type: Bug > Affects Versions: 1.6.1, 1.6.2, 1.7.0 > Reporter: Billie Rinaldi > Assignee: Billie Rinaldi > Fix For: 1.6.3, 1.7.1, 1.8.0 > > Attachments: ACCUMULO-3890.1.patch, ACCUMULO-3890.2.patch, > ACCUMULO-3890.3.patch, ACCUMULO-3890.4.patch, ACCUMULO-3890.5.patch > > Time Spent: 10m > Remaining Estimate: 0h > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
