This approach does not work well with dynamics > of the cluster where new nodes are being added and pipelines are destroyed. > New containers are not created until all the preallocated containers are > exhausted. > The Jira aims to establish a criteria in block allocation where first a > pipeline is selected amongst the available pipelines and then a container is > selected in that pipeline. In order to handle the dynamics of the cluster a > fixed interval pipeline creator job can be launched which creates pipelines > in the system. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
