To be precise, when u start your namenode it would construct it's namespace. As datanodes startup and send block reports the namespace gets constructed. During this time namenode is in safemode. If your namenode is insafe mode for long time that means some datanodes are yet to report their state.

Meta data is read-only, and block replication / removal is not taking place.

Especially rename, mkdir, and severals seems okay to be executed in safemode. I appreciate your help in advance. Sangmin -- Best regards, Edward J. Yoon [EMAIL PROTECTED] http://blog.udanax.org
