[jira] [Updated] (KAFKA-418) NullPointerException in ConsumerFetcherManager

     [ https://issues.apache.org/jira/browse/KAFKA-418?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jun Rao updated KAFKA-418:
--------------------------

    Attachment: kafka-418_v1.patch

Attach patch v1. The problem is that ConsumerFetcherManager cleared the partitionMap first, before closing the fetchers.
