Aviem Zur updated BEAM-1629: ---------------------------- Fix Version/s: First stable release > Metrics/aggregators accumulators should be instantiated before traversing > pipeline > ---------------------------------------------------------------------------------- > > Key: BEAM-1629 > URL: https://issues.apache.org/jira/browse/BEAM-1629 > Project: Beam > Issue Type: Bug > Components: runner-spark > Reporter: Aviem Zur > Assignee: Aviem Zur > Fix For: First stable release > > > 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. > This is fine for streaming branches of a pipeline as you probably did > something wrong, but for batch branches this should be allowed (In completely > batch pipelines accumulators are instantiated before traversal and everything > works fine, the issue occurs in streaming+batch combined pipelines) -- This message was sent by Atlassian JIRA (v6.3.15#6346)
