Can we trigger compilation again? Thanks for review. Now triggered compilation. And I triggerd compilation with command "git commit --amend && git push -f ". Is there any other way to trigger compilation? Thanks RBF: ConnectionManager creatorQueue should offer a pool that is not already in creatorQueue. -------------------------------------------------------------------------------------------- Key: HDFS-17311 URL: https://issues.apache.org/jira/browse/HDFS-17311 Project: Hadoop HDFS Issue Type: Improvement Reporter: liuguanghua Assignee: liuguanghua Priority: Major Labels: pull-request-available In the Router, find blow log 2023-12-29 15:18:54,799 ERROR org.apache.hadoop.hdfs.server.federation.router.ConnectionManager: Cannot add more than 2048 connections at the same time The log indicates that ConnectionManager.creatorQueue is full at a certain point. But my cluster does not have so many users cloud reach up 2048 pair of <user,nn>. This may be due to the following reasons: # ConnectionManager.creatorQueue is a queue that will be offered ConnectionPool if ConnectionContext is not enough. # ConnectionCreator thread will consume from creatorQueue and make more ConnectionContexts for a ConnectionPool. # Client will concurrent invoke for ConnectionManager.getConnection() for a same user. And this maybe lead to add many same ConnectionPool into ConnectionManager.creatorQueue. # When creatorQueue is full, a new ConnectionPool will not be added in successfully and log this error. This maybe lead to a really new ConnectionPool clould not produce more ConnectionContexts for new user. So this pr try to make creatorQueue will not add same ConnectionPool at once. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org > RBF: ConnectionManager creatorQueue should offer a pool that is not already > in creatorQueue. > -------------------------------------------------------------------------------------------- > > Key: HDFS-17311 > URL: https://issues.apache.org/jira/browse/HDFS-17311 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: liuguanghua > Assignee: liuguanghua > Priority: Major > Labels: pull-request-available > > In the Router, find blow log > > 2023-12-29 15:18:54,799 ERROR > org.apache.hadoop.hdfs.server.federation.router.ConnectionManager: Cannot add > more than 2048 connections at the same time > > The log indicates that ConnectionManager.creatorQueue is full at a certain > point.
