--------------------------------
Summary: Counter column has duplicate column names
Key: CASSANDRA-4711
URL: https://issues.apache.org/jira/browse/CASSANDRA-4711
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.1.5
Environment: CentOS 5.8 x86_64
Cassandra 1.1.5
Hector 1.1-2
Reporter: Shane
I have a column family whose comparator is DynamicCompositeType and validation
is CounterColumnType. During automated testing, there have been occasions
where a counter column is created twice, throwing off the query results for the
column.
Doing a 'get' via the cli, I see the following output for the row:
=> (counter=s@language:b@00000001:s@pt_BR, value=198)
=> (counter=s@language:s@possible, value=200)
=> (counter=s@language:b@00000001:s@pt_BR, value=0)
If I print out the byte value of the column names along with their MD5 sum I
see:
Name: [language, java.nio.HeapByteBuffer[pos=0 lim=4 cap=4], pt_BR]
Byte array:
ffffff8073086c616e67756167650ffffff80620400010ffffff80730570745f42520
MD5: 2db353a9a72a0d7cb6cb277ac5125653
Name: [language, possible]
Byte array: ffffff8073086c616e67756167650ffffff807308706f737369626c650
MD5: 82cad9b6a65c794e97cf1d4613e2e367
Name: [language, java.nio.HeapByteBuffer[pos=0 lim=4 cap=4], pt_BR]
Byte array:
ffffff8073086c616e67756167650ffffff80620400010ffffff80730570745f42520
MD5: 2db353a9a72a0d7cb6cb277ac5125653
Unfortunately, I have been unable to duplicate this manually or via a generic
test script and our QA department can only duplicate ~25% of the time.
