Your streams are probably hanging indefinitely.

IOW, the problem is not "decommission is slow" but "decommission will never

in 2.1.10 gives a non-infinite timeout for such streams... until then your
only option is to restart the node and restart the decomission.

FWIW, you don't really need to nohup, because having nodetool connecting to
JMX has no effect on whether the decommission completes or doesn't...
