Hdfs fSshell getmerge
Hello hadoop users, I have an idea about a small feature for the getmerge tool. I recently was in the need of using the new line option -nl because the files I needed to merge simply didn't had one. I was merging all the files from one directory and unfortunately this directory also included empty files, which effectively led to multiple newlines append after some files. I needed to remove them manually afterwards. In this situation it is maybe good to have another argument that allows skipping empty files. I just wrote down 2 change one could try at the end. Do you guys consider this as a good improvement to the command line tools? Thing one could try to implement this feature: The call for IOUtils.copyBytes(in, out, getConf(), false); doesn't return the number of bytes copied which would be convenient as one could skip append the new line when 0 bytes where copied Or one would check the file size before. Please let me know If you would consider this useful and is worth a feature ticket in Jira. Thank you Jan

Re: New consumer - partitions auto assigned only on poll
Hello Jason, Thanks for feedback. I've created ticket for this https://issues.apache.org/jira/browse/KAFKA-2359 Kind regards, Stevo Slavic. On Wed, Jul 22, 2015 at 6:18 PM, Jason Gustafson ja...@confluent.io wrote: Hey Stevo, That's a good point. I think the javadoc is pretty clear that this could return no partitions when the consumer has no active assignment, but it may be a little unintuitive to have to call poll() after subscribing before you can get the assigned partitions. I can't think of a strong reason not to go ahead with the assignment in subscriptions() other than to keep it non-blocking. Perhaps you can open a ticket and we can get feedback from some other devs?

After constructing KafakConsumer instance with configured consumer rebalance callback handler, and subscribing to a topic with consumer.subscribe(topic), retrieving subscriptions would return empty set and callback handler would not get called (no partitions ever assigned or revoked), no matter how long instance was up. Then I found by inspecting KafkaConsumer code that partition assignment will only be triggered on first poll, pollOnce has: // ensure we have partitions assigned if we expect to if (subscriptions.partitionsAutoAssigned()) coordinator.ensurePartitionAssignment(); Would it make sense to include this fragment in KafkaConsumer.subscriptions accessor as well?

New consumer - offset one gets in poll is not offset one is supposed to commit
Hello Apache Kafka community, Say there is only one topic with single partition and a single message on it. Result of calling a poll with new consumer will return ConsumerRecord for that message and it will have offset of 0. After processing message, current KafkaConsumer implementation expects one to commit not offset 0 as processed, but to commit offset 1 - next offset/position one would like to consume. Does this sound strange to you as well? Wondering couldn't this offset+1 handling for next position to read been done in one place, in KafkaConsumer implementation or broker or whatever, instead of every user of KafkaConsumer having to do it. Kind regards, Stevo Slavic.
Log Deletion Behavior
Hi all, I have a few broad questions on how log deletion works, specifically in conjunction with the log.retention.time setting. Say I published some messages to some topics when the configuration was originally set to something like log.retention.hours=168 (default). If I publish these messages successfully, then later set the configuration to something like log.retention.minutes=1, are those logs supposed to persist for the newest settings or the old settings? Right now my logs are refusing to delete themselves unless I specifically mark them for deletion -- is this the correct/anticipated/wanted behavior?

deleting data automatically
Hi, I am testing the kafka producer performance. So I created a queue and writes a large amount of data to that queue. Is there a way to delete the data automatically after some time, say whenever the data size reaches 50GB or the retention time exceeds 10 seconds, it will be deleted so my disk won't get filled and new data can't be written in? Thanks.!
Changing error codes from the simple consumer?
I am having a strange interaction with the simple consumer API in Kafka 0.8.2.
Running the following code:
public FetchedMessageList send(String topic, int partition, long offset, int
fetchSize) throws KafkaException {
try {
FetchedMessageList results = new FetchedMessageList();
FetchRequest req = new FetchRequestBuilder()
.clientId(clientId)
.addFetch(topic, partition, offset, fetchSize)
.minBytes(1)
.maxWait(250)
.build();
FetchResponse resp = consumer.fetch(req);
if(resp.hasError()) {
int code = resp.errorCode(topic, partition);
if (code == 9) {
logger.warn(Fetch response contained error code: {},
resp.errorCode(topic, partition));
} else {
throw new RuntimeException(String.format(Fetch response
contained error code %d, code));
}
}
Following a leader election, the FetchResponse has an error, and trips the
(code == 9) condition, causing the program to emit a message via logger.warn.
However, the emitted log message reads “Fetch response contained error code: 6”.
I looked over the Kafka source code and don’t see how resp.errorCode might
return a different value the second time.
Has anyone seen this before?
Thanks,
Matt Coolbeth
Re: Log Deletion Behavior
No. This should not happen. At Linkedin we just use the log retention hours. Try using that. Chang e it and bounce the broker. It should work.

Any tool to easily fetch a single message or a few messages starting from a given offset then exit after fetching said count of messages?
Hi, I notice the kafka-console-consumer.sh script has option to fetch a max # of messages, which can be 1 or more, and then exit. Which is nice. But as a high level consumer, it's missing option to fetch from given offset other than earliest latest offsets. Is there any off the shelf tool (CLI, simple script, etc.) that I can use to fetch 1 or more messages from a given offset of some topic as a consumer, then exit? Or do I have to write my own tool to do this from any of the kafka libraries in various languages? If the later, is there any where I can whip one up in fewest lines possible? I don't want to have to read up and spend time crafting up a tool for this if I don't have to. Wish this feature was already built in to the kafka toolchain. Regards, David
Re: Log Deletion Behavior
Okay, I will look into only using the hours setting, but I think that means the minimum a log can be stored is 1 hour right?

Re: deleting data automatically
You'll want to set the log retention policy via
log.retention.{ms,minutes,hours} or log.retention.bytes. If you want really
aggressive collection (e.g., on the order of seconds, as you specified),
you might also need to adjust log.segment.bytes/log.roll.{ms,hours} and
log.retention.check.interval.ms.
