Brandon Williams updated CASSANDRA-2810: ---------------------------------------- Attachment: 2810-v3.txt v3 also removes decomposing the values before inserting and instead forces them into a ByteBuffer with objToBB, since we actually don't care about the type. (why did we ever change this?) This means that a UDF that doesn't preserve the schema and hands us back DataByteArrays when we fed it specific types can't make us fail anymore. > RuntimeException in Pig when using "dump" command on column name > ---------------------------------------------------------------- > > Key: CASSANDRA-2810 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2810 > Project: Cassandra > Issue Type: Bug > Affects Versions: 0.8.1 > Environment: Ubuntu 10.10, 32 bits > java version "1.6.0_24" > Brisk beta-2 installed from Debian packages > Reporter: Silvère Lestang > Assignee: Brandon Williams > Attachments: 2810-v2.txt, 2810-v3.txt, 2810.txt > > > This bug was previously report on [Brisk bug > tracker|https://datastax.jira.com/browse/BRISK-232]. > In cassandra-cli: > {code} > [default@unknown] create keyspace Test > with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy' > and strategy_options = [{replication_factor:1}];
