Subject [jira] [Updated] (SPARK-6404) Call broadcast() in each interval for spark streaming programs.
Date Wed, 18 Mar 2015 20:58:40 GMT

     [ https://issues.apache.org/jira/browse/SPARK-6404?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yifan Wang updated SPARK-6404:
------------------------------
    Description: If I understand it correctly, Spark’s broadcast() function will be called
only once at the beginning of the batch. For streaming applications that need to run for 24/7,
it is often needed to update variables that shared by broadcast() dynamically. It would be
ideal if broadcast() could be called at the beginning of each interval.
