--------------------------------------------
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?
