Subject data node maintainance question
Date Wed, 22 Sep 2010 19:36:53 GMT

i have a datanode maintenance question.

if i bring a data node for memory upgrade down for several hours and then
return it back, i don't need to run decommission? decommission is only if i
want to get rid of that node for good and now want to re-distribute its
blocks, right?

Or i will be risking some sort of 'split brain' inconsistency?

Thank you.
