Date Mon, 06 Mar 2017 19:02:32 GMT

     [ https://issues.apache.org/jira/browse/BEAM-1629?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aviem Zur updated BEAM-1629:
----------------------------
    Description: Today aggregators and metrics accumulators are instantiated after pipeline
is traversed, and so, if code that runs on driver accesses these singletons but is not part
of a closure a {{NullPointerException}} is thrown.  (was: Today aggregators and metrics accumulators
are instantiated after pipeline is traversed, and so, if transform translations access these
singletons in code which runs on the driver, but is not part of a closure, a {{NullPointerException}}
is thrown.)
