Hi All,

=
1) What will happen if I run nodetool cleanup immediately af= ter bringing a new node up (i.e. before the key migration process is comple= ted) ?
        Will it cause some race conditions ? Or= will it result in some part of the space never be reclaimed ?
=

2) After adding a new machine, how can I make s= ure that the key migration is completed ? Should I run nodetool netstats on= all the nodes ? Is there any better way ?
