FAQ
Hi!

I have unbalanced disks on one of my nodes after a disk failure with
disk replacements.

http://wiki.apache.org/hadoop/FAQ#On_an_individual_data_node.2C_how_do_you_balance_the_blocks_on_the_disk.3F
has a solution, but it starts with "Take down HDFS".

Is that really necessary - shouldn't taking down just that datanode,
moving around the blocks, then start the datanode be good enough, or
will that mess up some datastructure in the namenode?

Thanks,
\EF
