[jira] [Commented] (STORM-869) kafka spout cannot fetch message if log size is above fetchSizeBytes

["Adrian Seungjin Lee (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STORM-869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14587624#comment-14587624 ] 

Adrian Seungjin Lee commented on STORM-869:
-------------------------------------------

You can reproduce this by setting fetchSizeBytes to reasonably small number, I think the default behavior should be modified to get at least one message from kafka, is it doable?

> let's say maxFetchSizeBytes is set to 1 megabytes, then if there exists a message that is bigger than 1 m, kafka spout just hangs and become inactive.
> This is both happening in Kafka spout for bolt/spout topology and also in trident spouts.
