upgrade fsimage

New Contributor

while we are upgrading hadoop, one recommendation is to take the current fsimage and upgrade it on a test machine to see if it upgrades as expected.   we dumped a current fsimage, but not sure how to upgrade the image only in test machine.   can you please provide some steps?

You can try running
hadoop namenode -upgrade (Namenode should be started with upgrade option after the distribution of new hadoop version.)
