Donald Smith updated CASSANDRA-8591:
------------------------------------
    Description: 
Often bootstrapping fails due to errors like "unable to find sufficient sources 
for streaming range". But cassandra is supposed to be fault tolerant, and it's 
supposed to have tuneable consistency.

If it can't find some sources, it should allow bootstrapping to continue, under 
control by parameters, and should print out a report about what ranges were 
missing.  For many apps, it's far better to bootstrap what's available then to 
fail flat.
