Wangda Tan updated HADOOP-15602: -------------------------------- Target Version/s: 3.1.2 (was: 3.1.1) > Support SASL Rpc request handling in separate Handlers > ------------------------------------------------------- > > Key: HADOOP-15602 > URL: https://issues.apache.org/jira/browse/HADOOP-15602 > Project: Hadoop Common > Issue Type: Improvement > Components: ipc > Reporter: Vinayakumar B > Assignee: Vinayakumar B > Priority: Major > Attachments: HADOOP-15602.01.patch > > > Right now, during RPC Connection establishment, all SASL requests are > considered as OutOfBand requests and handled within the same Reader thread. > SASL handling involves authentication with Kerberos and SecretManagers(for > Token validation). During this time, Reader thread would be blocked, hence > blocking all the incoming RPC requests on other established connections. Some > secretManager impls require to communicate to external systems (ex: ZK) for > verification. > SASL RPC handling in separate dedicated handlers, would enable Reader threads > to read RPC requests from established connections without blocking. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
