[~alexliu68] Oh, I was thinking that only thrift was affected by the CQL3 issue
and that it was why pig was not working. If Pig needs to be updated too (as you
say), I'll wait for that with hope that it will come soon… Can you change the
status of [CASSANDRA-5234|https://issues.apache.org/jira/browse/CASSANDRA-5234]
otherwise it won't be assigned unless there is another JIRA for that ?

Support cql3 table definitions in Hadoop InputFormat
Key: CASSANDRA-4421
URL: https://issues.apache.org/jira/browse/CASSANDRA-4421
Project: Cassandra
Issue Type: Improvement
Components: API
Affects Versions: 1.1.0
Environment: Debian Squeeze
Reporter: bert Passek
Labels: cql3
Fix For: 1.2.5
Attachments: 4421-1.txt, 4421-2.txt, 4421.txt
Hello,
i faced a bug while writing composite column values and following validation
on server side.
This is the setup for reproduction:
1. create a keyspace
create keyspace test with strategy_class = 'SimpleStrategy' and
strategy_options:replication_factor = 1;
2. create a cf via cql (3.0)
create table test1 (
a int,
b int,
c int,
primary key (a, b)
);
If i have a look at the schema in cli i noticed that there is no column
metadata for columns not part of primary key.
create column family test1
with column_type = 'Standard'
and comparator =
'CompositeType(org.apache.cassandra.db.marshal.Int32Type,org.apache.cassandra.db.marshal.UTF8Type)'
and default_validation_class = 'UTF8Type'
and key_validation_class = 'Int32Type'
and read_repair_chance = 0.1
and dclocal_read_repair_chance = 0.0
and gc_grace = 864000
and min_compaction_threshold = 4
and max_compaction_threshold = 32
and replicate_on_write = true
and compaction_strategy =
'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy'
and caching = 'KEYS_ONLY'
and compression_options = {'sstable_compression' :
'org.apache.cassandra.io.compress.SnappyCompressor'};
Please notice the default validation class: UTF8Type
Now i would like to insert value 127 via cassandra client (no cql, part of
mr-jobs). Have a look at the attachement.
Batch mutate fails:
InvalidRequestException(why:(String didn't validate.) [test][test1][1:c]
failed validation)
A validator for column value is fetched in
ThriftValidation::validateColumnData which returns always the default
validator which is UTF8Type as described above (The ColumnDefinition for
given column name c is always null)
In UTF8Type there is a check for
if (b 127)
return false;
Anyway, maybe i'm doing something wrong, but i used cql 3.0 for table
creation. I assigned data types to all columns, but i can not set values for
a composite column because the default validation class is used.
I think the schema should know the correct validator even for composite
columns. The usage of the default validation class does not make sense.
Best Regards
Bert Passek

Summary: nodetool repair hanging on multi sites config
Key: CASSANDRA-5550
URL: https://issues.apache.org/jira/browse/CASSANDRA-5550
Project: Cassandra
Issue Type: Bug
Components: Tools
Affects Versions: 1.2.4
Reporter: Kévin LOVATO
We recently added a new datacenter to our cluster, and we want some keyspaces
to be replicated to it, but not all.
So some of our Keyspaces have a replication factor of {code}{ dcMain: 3, dcNew:
1 }{code}and some have {code}{ dcMain: 3 }{code}We then ran a nodetool repair
on one of the new servers so the data would be replicated correctly, but it
just hung.
After some investigation, we saw that if a Keyspace didn't have replication
info for dcNew, or a replication factor of 0, a nodetool repair from the new
servers would hang (nothing concerning repair in the logs, not even in DEBUG
level).
On the other hand, it works properly if the Keyspace has a replica in dcNew or
if the repair is called from dcMain.
We might be doing something wrong, but I don't think nodetool should hang
silently even if something is going wrong.
Nodetool repair -pr also works in all situations, but it seems that it is not
copying the data to the new datacenter at all, it runs and logs that the
keyspace is up to date after receiving the merkle trees, even though nothing is
actually copied on the disk, even after flushing (maybe an unrelated issue,
should I open another ticket?).

compaction?
Concurrent secondary index updates remove rows from the index

Existing rows disappear from secondary index when doing simultaneous updates
of a row with the same secondary index value.
Here is a little pycassa script that reproduces a bug. The script inserts 4
rows with same secondary index value, reads those rows back and check that
there are 4 of them.
Please run two instances of the script simultaneously in two separate
terminals in order to simulate concurrent updates:
{code}

pool = pycassa.ConnectionPool('ks123')

cf.insert(str(rowKey), {'indexedColumn': 'indexedValue'})
index_expression = create_index_expression('indexedColumn',
'indexedValue')
index_clause = create_index_clause([index_expression])
rows = cf.get_indexed_slices(index_clause)
length = len(list(rows))
if length == 4:
pass
else:
print 'found just %d rows out of 4' % length
