Description

Create a two node cluster, create a keyspace, don't create any tables. Initiate a repair:

04:32 PM:~$ ccm create -v git:cassandra-2.1 test -n 2 -s
Fetching Cassandra updates...
Current cluster is now: test
04:33 PM:~$ ccm node1 cqlsh
Connected to test at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 2.1.2-SNAPSHOT | CQL spec 3.2.0 | Native protocol v3]
Use HELP for help.
cqlsh> create KEYSPACE test WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 2};
cqlsh> 
04:34 PM:~$ ccm node1 nodetool -- repair
[2015-01-27 16:34:11,741] Nothing to repair for keyspace 'system'
[2015-01-27 16:34:11,748] Starting repair command #1, repairing 2 ranges for keyspace test (parallelism=SEQUENTIAL, full=true)

The repair hangs.

Do the same thing but add a table, and the repair completes very quickly.
