This puts extra load to name node since all writers need to > make name node calls to open files. > We propose the following approach to this problem: > For writers at back end, they extract meta information from job configuration > object directly, rather than making name node calls and going to HDFS disk to > fetch the information. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
