How much time does normal hdfs safemode recovery takes?
If you don't have secondary namenode set up it has to replay namenode operations, the time to recover then depends on how long the cluster has been up. 40 minutes is entirely possible. Don't panic and kill the process, incidentally, that only makes things worse.
Will there be any speedup, by not starting task trackers till job tracker is started?
