Hi, For some reason, all PIDs file are missing in my cluster, I have to manually kill all java processes on all machines, then I restarted the HDFS, but it took so long time in applying changes in edit log file, so my question is how can I reduce the delay? My understanding is as follows, could someone please give some comments on it?
hadoop dfsadmin -safemode enter
#save current in-mem data to image file and reset edit log
hadoop dfsadmin -saveNamespace
