Thrift gen problem with cassandra.thrift
I installed thrift successfully on Snow Leaopard. However, when I run
*thrift -gen java interface/cassandra.thrift* with Cassandra 0.6.5, I get an
error which reads as follows:
....apache-cassandra-0.6.5/interface/cassandra.thrift:303] error: identifier
ONE is unqualified!
Line 303 of cassandra.thrift is highlighted in the text below:
296 /**
297 Get the Column or SuperColumn at the given column_path. If no value
is present, NotFoundException is thrown . (This is
298 the only method that can throw an exception under non-failure
conditions.)
299 */
300 ColumnOrSuperColumn get(1:required string keyspace,
301 2:required string key,
302 3:required ColumnPath column_path,
*303 4:required ConsistencyLevel
consistency_level=ONE)*
304 throws (1:InvalidRequestException ire,
2:NotFoundException nfe, 3:UnavailableException ue , 4:TimedOutException
te),
305
Could somebody please help resolve this problem and also explain what's
going on here.
Thanks, Shashank

Did you build thrift with the specific subversion revision that Cassandra uses?

I finally grabbed Cassandra off the trunk to make things work so I guess it
is 0.7. If I start the same server and connect to it, should things work? I
am happy using pycassa or telephus but I had Thrift installed for things
beyond Cassandra (for example for Hypertable) and I was hoping that
installation would work with multiple products that use Thrift. Now I know
it doesn't.

Is it possible that you are somehow using the 0.7 generated cassandra
module, perhaps from some previous installation of a client library? In
0.7, insert takes only 5 arguments.
Also, is there any particular reason that you are using raw Thrift and not a
high level client like pycassa, telephus, etc?

Re: Thrift gen problem with cassandra.thrift
Posted by Shashank Tiwari <ts...@gmail.com>.
Jeremy and Aaron,
Thanks for your help.
I had already installed Thrift on my Snow Leopard so I thought running *thrift
-gen cassandra.thrift* file would work. However as the wiki suggests it
appears only a specific version of Thrift work with a particular Cassandra
version. So I checked out the matching version of Thrift. Even after getting
the exact version of Thrift though, getting it to work wasn't straight
forward and in fact its still throwing errors.
Aaron's suggestions of using the ant task (*ant gen-thrift-py*) seemed much
smoother but then that task does not generate the python thrift module, it
only generates the cassandra module.
So I used a mix and match of both methods and finally have both the thrift
and the cassandra modules. However, it now seems there is a mismatch in the
API. I ran the python example from
http://wiki.apache.org/cassandra/ThriftExamples#Python and ended up with the
following errors:
Traceback (most recent call last):
File "cassandra_client.py", line 52, in <module>
main()
File "cassandra_client.py", line 35, in main
ConsistencyLevel.ZERO)
TypeError: insert() takes exactly 5 arguments (7 given)
------
Line 35 of cassandra_client.py is the same as line 35 of the python example
on the Cassandra wiki Thrift Examples page. Its the line in bold in the code
snippet below:
try:
transport.open()
#Insert the data into Keyspace 1
*client.insert(keyspace,*
* key,*
* column_path,*
* value,*
* timestamp,*
* ConsistencyLevel.ZERO)*
#Query for data
column_parent = ColumnParent(column_family="Standard1")
slice_range = SliceRange(start="", finish="")
predicate = SlicePredicate(slice_range=slice_range)
result = client.get_slice(keyspace,
key,
column_parent,
predicate,
ConsistencyLevel.ONE)
pp.pprint(result)
except Thrift.TException, tx:
print 'Thrift: %s' % tx.message
finally:
Can somebody please help and make sense of this. Isn't there a more simple
and straightforward way getting Thrift to work with Cassandra? If not, why
not?
Thanks, Shashank

I normally get the source download, then run ant gen-thrift-py
Is there a reason you want to build it manually?
