Vinod Kumar Vavilapalli commented on MAPREDUCE-6248: ---------------------------------------------------- Why not have a public API in DistCp and use that programmatically instead of persisting IDs into files and then reading them? > Persist DistCp job id in the staging directory > ---------------------------------------------- > > Key: MAPREDUCE-6248 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6248 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: distcp > Reporter: Jing Zhao > Assignee: Jing Zhao > > Currently the DistCp is acting as a tool and the corresponding MapReduce Job > is created and used inside of its {{execute}} method. It is thus difficult > for external services to query its progress and counters. It may be helpful > to persist the job id into a file inside its staging directory. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
