I saw a hang like this last night in some testing and I decided to let it run. About 3 hours later it finally completed...this still seems out-of-spec. I'll try to get some clean logs for you and send them along. Thanks, C G dhruba Borthakur <[EMAIL PROTECTED]> wrote: Hi CG, When the shell hangs, can you pl get the following: 1. The namenode log file 2. The namenode stack dump. This can be generated by running the command "jstack ". You will typically find the jstack utility in the same directory where the "java" binary is installed. Thanks, dhruba 1. Hanging shell commands: Our system is all script-driven. The first thing our main driver does when it starts up is delete old datasets in preparation for creating new ones. A command like this will hang forever about 5% of the time: bin/hadoop dfs -rmr /import/data/20071030 --------------------------------- Get easy, one-click access to your favorites.
