Description

Hi,
I`m running one node cluster(issue occurs also on other cluster(which has 2 nodes)) on snapshot from cassandra-1.1 branch(i used 449e037195c3c504d7aca5088e8bc7bd5a50e7d0 commit).
i have simple CF, definition of TestCF:

[default@test_keyspace] describe Test_CF;
    ColumnFamily: Test_CF
      Key Validation Class: org.apache.cassandra.db.marshal.UTF8Type
      Default column value validator: org.apache.cassandra.db.marshal.UTF8Type

I`m trying to add new row(log from cassandra-cli, note that there is index on test_index):

[default@test_keyspace] list Test_CF;              
Using default limit of 100
