Hi. We are running Hadoop 0.18.3 and noticed a strange issue when one of our machines went out of disk yesterday. If you can see the table below it would display that the server "mapredcoord" is 66.91% allocated and the others are almost empty. How can that be ?
Any information about this would be very helpful. mapredcoord is as well our jobtracker. //Marcus Node Last Contact Admin State Size (GB) Used (%) Used (%) Remaining (GB) Blocks mapredcoord<http://mapredcoord:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>2In Service416.6966.91 90.9419806 mapreduce2<http://mapreduce2:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>2In Service416.696.71 303.54456 mapreduce3<http://mapreduce3:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>2In Service416.690.44 351.693975 mapreduce4<http://mapreduce4:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>0In Service416.690.25 355.821549 mapreduce5<http://mapreduce5:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>2In Service416.690.42 347.683995 mapreduce6<http://mapreduce6:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>0In Service416.690.43 352.73982 mapreduce7<http://mapreduce7:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>0In Service416.690.5 351.914079 mapreduce8<http://mapreduce8:50076/browseDirectory.jsp?namenodeInfoPort=50070&dir=%2F>1In Service416.690.48 350.154169 -- Marcus Herou CTO and co-founder Tailsweep AB +46702561312 [email protected] http://www.tailsweep.com/ http://blogg.tailsweep.com/
