Short reads protection results in returning more columns than asked for
-----------------------------------------------------------------------
Key: CASSANDRA-3303
URL: https://issues.apache.org/jira/browse/CASSANDRA-3303
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0.0
Reporter: Sylvain Lebresne
Priority: Minor
Fix For: 1.0.0
When we detect a short read (in SP.fetchRows), we retry a new command created
by:
{noformat}
logger.debug("detected short read: expected {} columns, but only resolved {}
columns", sliceCommand.count, liveColumnsInRow);
int retryCount = sliceCommand.count + sliceCommand.count - liveColumnsInRow;
SliceFromReadCommand retryCommand = new SliceFromReadCommand(command.table,
command.key,
command.queryPath,
sliceCommand.start,
sliceCommand.finish,
sliceCommand.reversed,
retryCount);
{noformat}
That is, in that new command, the count is greater than what asked in the
initial command. But we never cut back the result of that new retried query.
