Re: difficulty to delete a topic because of its syntax

[Gwen Shapira]

Just note that in general doing what Todd advice is pretty risky.
We've seen controllers get into all kinds of weird situations when
topics were deleted from ZK directly (including getting stuck in an
infinite loop, deleting unrelated topics and all kinds of strangeness)
- we have no tests for those scenarios so behavior can get really
unexpected.

That’s great to hear!

Does this mean that the next release (after 0.10.1.0, maybe ~Feb?) might remove 
altogether the requirement that Streams apps be able to access ZooKeeper 
directly? Or is this simply a solid step in that direction? It’s good news 
either way; really I’m just curious.

Thanks!

Yes in fact,

The topic in question was a name of a store.

Ok i will do it for th matter of JIRA.

It's worth mentioning that Streams is in the process of transitioning from
updating ZooKeeper directly to using the newly introduced create topics and
delete topics protocol requests. It was too late for 0.10.1.0, but should
land in trunk soonish.

Re: difficulty to delete a topic because of its syntax

[Ismael Juma]

It's worth mentioning that Streams is in the process of transitioning from
updating ZooKeeper directly to using the newly introduced create topics and
delete topics protocol requests. It was too late for 0.10.1.0, but should
land in trunk soonish.

Re: difficulty to delete a topic because of its syntax

[Yuto KAWAMURA]

I guess this topic is created by Kafka Streams.
Kafka Streams has it's own topic creation(zookeeper node creation)
implementation and not using core's AdminUtils to create internal use
topics such as XX-changelog:
https://github.com/apache/kafka/blob/trunk/streams/src/main/java/org/apache/kafka/streams/processor/internals/InternalTopicManager.java#L208
In AdminUtils it has topic name
validation(https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/common/Topic.scala#L33-L47)
logic but I don't see similar thing in Kafka Streams version as I read
the code briefly.
Since the topic name is created by the store name which is an
arbitrary string given by users, this could happen if you give a
string that contains whitespace as a name of state store.

Re: difficulty to delete a topic because of its syntax

[Rajini Sivaram]

Hamza,

Can you raise a JIRA with details on how the topic was created by Kafka
with an invalid name? Sounds like there might be a missing validation
somewhere.

Rajini

RE: difficulty to delete a topic because of its syntax

[Hamza HACHANI]

Thanks Todd,


I've resolved it by suing what you told me.

Thanks very much. But i think that there is a problem with kafka by letting the 
saving names of topic and logs where there is a space as i showes in the images.

Have a good day to you all.

You *could* go in to zookeeper and nuke the topic, then delete the files on
disk

Slightly more risky but it should work

Re: difficulty to delete a topic because of its syntax

[Manikumar]

Kafka doesn't support white spaces in topic names.  Only support '.', '_'
and '-' these are allowed.
Not sure how you got white space in topic name.

Try putting "" or '' around the string when running the command.
