Ming-Lung Weng updated FLUME-2772:
----------------------------------
Description:
I found SpoolDirectorySource drop Event when channel(memory channel i used) is
full
at org.apache.flume.source.SpoolDirectorySource.run()
{code:title=Bar.java|borderStyle=solid}
while (!Thread.interrupted()) {
List<Event> events = reader.readEvents(batchSize);
if (events.isEmpty()) {
break;
}
sourceCounter.addToEventReceivedCount(events.size());
sourceCounter.incrementAppendBatchReceivedCount();
try {
getChannelProcessor().processEventBatch(events);
reader.commit();
} catch (ChannelException ex) {
logger.warn("The channel is full, and cannot write data now. The " +
"source will try again after " + String.valueOf(backoffInterval) +
" milliseconds");
hitChannelException = true;
if (backoff) {
TimeUnit.MILLISECONDS.sleep(backoffInterval);
backoffInterval = backoffInterval << 1;
backoffInterval = backoffInterval >= maxBackoff ? maxBackoff :
backoffInterval;
}
continue;
}
backoffInterval = 250;
sourceCounter.addToEventAcceptedCount(events.size());
sourceCounter.incrementAppendBatchAcceptedCount();
}
{code}
SpoolDirectorySource sleep a backoff time and re-calculate backoff time,
and continue to read next event DO NOTHING with the event that not put into
channel
There is no exception but only logger.warn that sound not important
This is a bug to me, but I'm not sure is this a bug
I use a simple while loop to fix this, just like
boolean eventPushed = false;
while(!eventPushed) {
[ the try-catch block for put event into channel ]
}
