Exceptions during inserting emtpy string as column value on indexed column
--------------------------------------------------------------------------

                 Key: CASSANDRA-4031
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4031
             Project: Cassandra
          Issue Type: Bug
            Reporter: Mariusz


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:
{noformat}
[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
      Columns sorted by: org.apache.cassandra.db.marshal.UTF8Type
      GC grace seconds: 864000
      Compaction min/max thresholds: 4/32
      Read repair chance: 1.0
      DC Local Read repair chance: 0.0
      Replicate on write: true
      Caching: KEYS_ONLY
      Bloom Filter FP chance: default
      Built indexes: [Test_CF.Test_CF_test_index_idx]
      Column Metadata:
        Column Name: test_index
          Validation Class: org.apache.cassandra.db.marshal.UTF8Type
          Index Name: Test_CF_test_index_idx
          Index Type: KEYS

      Compression Options:

{noformat}
I`m trying to add new row(log from cassandra-cli, note that there is index on test_index):
{noformat}
[default@test_keyspace] list Test_CF;              
Using default limit of 100
