Subject [jira] Commented: (CASSANDRA-1073) EOFException with Cassandra.Client.get_range_slices() API
Date Tue, 25 May 2010 03:47:26 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1073?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12870974#action_12870974
] 

Jonathan Ellis commented on CASSANDRA-1073:
-------------------------------------------

matthew, i think you and frank are looking at two different things.  it sounds to me like
frank is saying, "if I do thus and so [which involves killing the SERVER] I get corrupt sstables
that generate EOFexception when read, so no response is ever sent for WRH to see."

you're saying "if i kill the client the server logs EOFexception somewhere in the thrift code
or otherwise errors out trying to send the reply to the client [your WRH thing]" which makes
total sense.

> Below is the snippet I tried to run. The keyspace is named 'Keyspac1', with only 1 column
family named 'CF1'. 
> 		ColumnParent cp = new ColumnParent("CF1");
> 		
> 		SlicePredicate predicate = new SlicePredicate();
> 		SliceRange sliceRange = new SliceRange();
> 		sliceRange.setStart(new byte[0]);
> 		sliceRange.setFinish(new byte[0]);
> 		predicate.setSlice_range(sliceRange);
> 		
> 		KeyRange range = new KeyRange(10);
> 		range.setStart_key("".getBytes());
> 		range.setEnd_key("".getBytes());
> 		
> 		client.set_keyspace(keyspace);
> 		List<KeySlice> slices = client.get_range_slices(cp, predicate, range, ConsistencyLevel.ONE);
> Then an EOFException was spit out. For readability, it is included in the next comment.
