json2sstable fails to create sstable from json file
---------------------------------------------------

                 Key: CASSANDRA-2188
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2188
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
    Affects Versions: 0.7.2
         Environment: linux
            Reporter: Shotaro Kamio


I have a json file created with sstable2json for a column family of super column type. But
json2sstable failed to create sstable from the file. It's because file format is wrong. 

 WARN 11:41:55,141 Schema definitions were defined both locally and in cassandra.yaml. Definitions
in cassandra.yaml were ignored.

When I looked at the file, I found that a comma is missing between super columns. The part
of data is like this: 

["756e697473",
 "32",
 1297926692097000, false]]}"32303036303830373135303030302f313030303030303030302d32303036313030322d303030303030303639382d612f30":
{
"deletedAt": -9223372036854775808,
 "subColumns": [["5f64656c",
 "",
 1297926692097000,
 false],

You'll see no comma between } and ".
