Using Cassandra via the Erlang Thrift Client API (HOW ??)
Hi,
I've been trying to piece together some notion of how to use cassandra from
an erlang client.
So far I have managed to come up with the following, but it doesn't work.
Unfortunately there does not seem to be any decent documentation on the
subject I can find with googling so I'm hoping some more experienced members
of this mailing list can point out what I'm doing wrong.
I'm using cassandra 0.5, and I think the latest version of thrift.
I generated the thrift erlang client code using:
$ thrift -r --gen erl cassandra.thrift
And compiled and copied that into my ebin area, along with the rest of the
thrift erlc library code.
I start cassandra using its default config bin/cassandra -f and there are no
apparent errors:
$ bin/cassandra -f
Listening for transport dt_socket at address: 8888
INFO - Sampling index for
/var/lib/cassandra/data/system/LocationInfo-9-Data.db
INFO - Replaying /var/lib/cassandra/commitlog/CommitLog-1267655779083.log
INFO - Log replay complete
INFO - Saved Token found: 141354730401634313333347303685581151939
INFO - Starting up server gossip
INFO - Cassandra starting up...
then after a few seconds, it displays this:
Debugger failed to attach: timeout during handshake
Then from an erl vm I try the following:
rr(cassandra_types).
{ok, C} = thrift_client:start_link("localhost",8888, cassandra_thrift).
thrift_client:call( C,
'insert',
[ "Keyspace1",
"1",
#columnPath{column_family="Standard1", column="email"},
"ted@example.com",
1,
1
] ).
Unfortunately, although I get a cassandra_thrift client connection, the call
to insert fails with :
=ERROR REPORT==== 4-Mar-2010::07:57:50 ===
** Generic server <0.333.0> terminating

You probably need to switch the server to framed thrift mode.

Greetings,
I am also exploring erlang and cassandra via thrift..
but when inserting i've encountered this error.

Thanks for the feedback, I've made this more clear in
https://issues.apache.org/jira/browse/CASSANDRA-849 on the 0.6 branch.

That would be great!

Hi All,
Many thanks for the responses. You helped enormously. I was in fact talking
to the wrong port. It should have been 9160 rather than 8888.
I just assumed that the port the cassandra server displayed when starting up
was the one I should be talking to, my bad. I should have read the config
file.
Once I have something working I'll write a new post back with a couple of
examples here to help future newbies on how to talk to cassandra from
erlang, since those examples are not present on the cassandra/thrift wiki as
far as I can tell.
Thanks,
Jason

I think you want port 9160, not 8888... dt_socket != thrift.

A code patch to improve the startup messages might be very useful as well.

Hi All,
Many thanks for the responses. You helped enormously. I was in fact talking
to the wrong port. It should have been 9160 rather than 8888.
I just assumed that the port the cassandra server displayed when starting up
was the one I should be talking to, my bad. I should have read the config
file.
Once I have something working I'll write a new post back with a couple of
examples here to help future newbies on how to talk to cassandra from
erlang, since those examples are not present on the cassandra/thrift wiki as
far as I can tell.

Hi JT,
Is 8888 the thrift port or Cassandra's internal protocol? It's been a while
since I used Cassandra, but I thought that was the port for gossip, etc?

Hi,
I've been trying to piece together some notion of how to use cassandra from
an erlang client.
So far I have managed to come up with the following, but it doesn't work.
Unfortunately there does not seem to be any decent documentation on the
subject I can find with googling so I'm hoping some more experienced members
of this mailing list can point out what I'm doing wrong.
I'm using cassandra 0.5, and I think the latest version of thrift.
I generated the thrift erlang client code using:
$ thrift -r --gen erl cassandra.thrift
And compiled and copied that into my ebin area, along with the rest of the
thrift erlc library code.
I start cassandra using its default config bin/cassandra -f and there are no
apparent errors:
$ bin/cassandra -f
Listening for transport dt_socket at address: 8888
INFO - Sampling index for
/var/lib/cassandra/data/system/LocationInfo-9-Data.db
INFO - Replaying /var/lib/cassandra/commitlog/CommitLog-1267655779083.log
INFO - Log replay complete
INFO - Saved Token found: 141354730401634313333347303685581151939
INFO - Starting up server gossip
INFO - Cassandra starting up...
then after a few seconds, it displays this:
Debugger failed to attach: timeout during handshake
Then from an erl vm I try the following:
rr(cassandra_types).
{ok, C} = thrift_client:start_link("localhost",8888, cassandra_thrift).
thrift_client:call( C,
'insert',
[ "Keyspace1",
"1",
#columnPath{column_family="Standard1", column="email"},
"ted@example.com",
1,
1
] ).
Unfortunately, although I get a cassandra_thrift client connection, the call
to insert fails with :
=ERROR REPORT==== 4-Mar-2010::07:57:50 ===

Cassandra itself reports nothing.
