Subject [jira] Commented: (CASSANDRA-1073) EOFException with Cassandra.Client.get_range_slices() API
Date Tue, 25 May 2010 04:05:24 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1073?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12870978#action_12870978
] 

Matthew F. Dennis commented on CASSANDRA-1073:
----------------------------------------------

Just to be clear, the test I automated:

parent process starts Cassandra server
parent process starts python thrift client in separate process
client loops inserting data
parent process sends SIGKILL to client in the middle of looping
parent process sends SIGTERM to server (is this not a clean shutdown?)
parent process starts server again
parent process connects to server over thrift from python
parent process issues get_range_slice and receives TimedOutException

As I understood Frank, he believed the issue to be that CliMain didn't call disconnect because
it was killed from Eclipse.  When he explicitly typed "exit" in the CLI, CliMain called disconnect
and the problem did not present himself (even though presumably he restarted Cassandra in
the same way).

Should I be looking at killing the server instead?

> 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.
