If the mover exit due to failure, it should exit with an error state like balancer. Mover is already handling this.. {code} try { final Map<URI, List<Path>> map = getNameNodePathsToMove(conf, args); return Mover.run(map, conf); } catch (IOException e) { System.out.println(e + ". Exiting ..."); return ExitStatus.IO_EXCEPTION.getExitCode(); } catch (InterruptedException e) { System.out.println(e + ". Exiting ..."); return ExitStatus.INTERRUPTED.getExitCode(); } catch (ParseException e) { System.out.println(e + ". Exiting ..."); return ExitStatus.ILLEGAL_ARGUMENTS.getExitCode(); } catch (IllegalArgumentException e) { System.out.println(e + ". Exiting ..."); return ExitStatus.ILLEGAL_ARGUMENTS.getExitCode(); } finally { System.out.format("%-24s ", DateFormat.getDateTimeInstance().format(new Date())); System.out.println("Mover took " + StringUtils.formatTime(Time.monotonicNow()-startTime)); } {code} Other comment fixed in new patch.... > HDFS Mover tool should exit after some retry when failed to move blocks. > ------------------------------------------------------------------------ > > Key: HDFS-8143 > URL: https://issues.apache.org/jira/browse/HDFS-8143 > Project: Hadoop HDFS > Issue Type: Bug > Components: balancer & mover > Affects Versions: 2.6.0 > Reporter: surendra singh lilhore > Assignee: surendra singh lilhore > Priority: Blocker > Attachments: HDFS-8143.patch, HDFS-8143_1.patch > > > Mover is not coming out in case of failed to move blocks. > {code} > hasRemaining |= Dispatcher.waitForMoveCompletion(storages.targets.values()); > {code} > {{Dispatcher.waitForMoveCompletion()}} will always return true if some blocks > migration failed.
