[jira] [Created] (CASSANDRA-3360) Read data inconsistancy in
Cassandra 1.0.0-rc2
Read data inconsistancy in Cassandra 1.0.0-rc2
----------------------------------------------
Key: CASSANDRA-3360
URL: https://issues.apache.org/jira/browse/CASSANDRA-3360
Project: Cassandra
Issue Type: Bug
Components: API
Affects Versions: 1.0.0
Reporter: Gopalakrishnan Rajagopal
When qsuper column for a particular key is being queried
using hector-core-0.8.0-2,
the data retrieved is inconsistent. I mean, for the key that I use to fetch
data, there are 7 sub columns actually. But the query returns 1 or 3 sub
columns depending on which nodes respond to it. (I tested by bringing down
each one of the three nodes in turn).
When I tried to fetch the data for the same key using cassandra-cli tool, I
get all the 7 sub columns for both the consistancy levels ONE and QUORUM.
Below is the code that I used to fetch data
superColumnQuery = HFactory.createSuperColumnQuery
(keyspaceOperator,
stringSerializer,
stringSerializer, stringSerializer, stringSerializer);
superColumnQuery.setColumnFamily(cfName).setKey
(key).setSuperName(scName);
result=superColumnQuery.execute();
superColumn=result.get();
columnList=superColumn.getColumns();

-----------------------------------------------------
I am not too sure... the same hector version and code works with 1.0.0-beta1 version though. So this just is a compatibilty issue with 1.0.0-rc2?

-------------------------------------------
If the CLI is behaving correctly, it sounds like a Hector bug?
