[jira] [Updated] (KAFKA-3398) avoid just sending to one partition when record key is empty string

     [ https://issues.apache.org/jira/browse/KAFKA-3398?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Xin Wang updated KAFKA-3398:
----------------------------
    Description: Now the DefaultPartitioner, if record key==null, choose a partition in a round-robin fashion; else choose a partition based on a hash of the key. But the producer will just send messages to one partition(partition index is 1) when key is an empty string "". We can add a check to avoid this.
