             Summary: sstabledump JSON fails after row tombstone
                 Key: CASSANDRA-12418
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12418
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
            Reporter: Keith Wansbrough


sstabledump fails in JSON generation on an sstable containing a row deletion, using Cassandra 3.10-SNAPSHOT accf7a4724e244d6f1ba921cb11d2554dbb54a76 from 2016-07-26.

There are two exceptions displayed:
* Fatal error parsing partition: aye org.codehaus.jackson.JsonGenerationException: Can not start an object, expecting field name
* org.codehaus.jackson.JsonGenerationException: Current context not an ARRAY but OBJECT

Steps to reproduce:
{code}
cqlsh> create KEYSPACE foo WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};
cqlsh> create TABLE foo.bar (id text, str text, primary key (id));
cqlsh> insert into foo.bar (id, str) values ('aye', 'alpha');
cqlsh> insert into foo.bar (id, str) values ('bee', 'beta');
cqlsh> delete from foo.bar where id = 'bee';
cqlsh> insert into foo.bar (id, str) values ('bee', 'beth');
cqlsh> select * from foo.bar;

 id  | str
-----+-------
 bee |  beth
 aye | alpha

(2 rows)
cqlsh> 
{code}

Now find the sstable:
{code}
$ cassandra/bin/nodetool flush
$ cassandra/bin/sstableutil foo bar
[..]
Listing files...
[..]
/home/kw217/cassandra/data/data/foo/bar-407c56f05e1a11e6835def64bf5c656e/mb-1-big-Data.db
[..]
{code}

Now check with sstabledump \-d. This works just fine.
{code}
$ cassandra/tools/bin/sstabledump -d /home/kw217/cassandra/data/data/foo/bar-407c56f05e1a11e6835def64bf5c656e/mb-1-big-Data.db
[bee]@0 deletedAt=1470737827008101, localDeletion=1470737827
[bee]@0 Row[info=[ts=1470737832405510] ]:  | [str=beth ts=1470737832405510]
[aye]@31 Row[info=[ts=1470737784401778] ]:  | [str=alpha ts=1470737784401778]
{code}

Now run sstabledump. This should work as well, but it fails as follows:
{code}
$ cassandra/tools/bin/sstabledump /home/kw217/cassandra/data/data/foo/bar-407c56f05e1a11e6835def64bf5c656e/mb-1-big-Data.db

If possible, please can this be fixed in the 3.0.x stream as well as trunk?
