How to determine hdfs metadata upgrade complete in hadoop 3.0?
Hi I am upgrading from hadoop 2.6 to hadoop 3.0. In the process, I am upgrading HDFS metadata by executing the below command. sudo -u hdfs hdfs --daemon start namenode -upgrade -renameReserved I am not able to locate any upgradeProgress command. How can I determine that the metadata upgrade is complete? Thanks,

This kind of weirdness is indicative of having YARN_CONF_DIR defined somewhere. - To unsubscribe, e-mail: user-unsubscr...@hadoop.apache.org For additional commands, e-mail: user-h...@hadoop.apache.org
Hadoop 3.0 doesn't detect the correct conf folder
I tried the hadoop 3.0, and can start dfs properly, but when I start yarn, it fails with the following error ERROR: Cannot find configuration directory "/Users/jzhang/Java/lib/hadoop-3.0.0/conf" Actually, this is not the correct conf folder. It should be /Users/jzhang/Java/lib/hadoop-3.0.0/etc/hadoop. hdfs could detect that correctly, but seems yarn couldn't, might be something wrong in yarn starting script.
