Ahmed Hussein created HADOOP-17358: -------------------------------------- Summary: Improve excessive reloading of Configurations Key: HADOOP-17358 URL: https://issues.apache.org/jira/browse/HADOOP-17358 Project: Hadoop Common Issue Type: Bug Components: conf Reporter: Ahmed Hussein Assignee: Ahmed Hussein
[~daryn] reported that adding a new resource to a conf forces a complete reload of the conf instead of just loading the new resource. Instantiating a {{SSLFactory}} adds a new resource for the ssl client/server file. Formerly only the KMS client used the SSLFactory but now TLS/RPC uses it too. The reload is so costly that RM token cancellation falls behind by hours or days. The accumulation of uncancelled tokens in the KMS rose from a few thousand to hundreds of thousands which risks ZK scalability issues causing a KMS outage. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
