Subject Re: Bootstrapping stays stuck
Date Wed, 15 Sep 2010 18:43:39 GMT
This problem still stays unresolved despite numerous restarts to the
cluster. I cant seem to find a way out of this one, and I am not really
looking for a workaround, kinda need this to work if i need to go to
production.

Turned on the ALL logging in log4j, and now I see the following exception
(EOFException) on the destination. After receiving each file, it seems to be
throwing this exception. The transfer is successful except for this
exception. The source successful declares the transfer complete. But the
destination does not move out of the bootstrapping mode, and just sits
there.
