Impala 2.9.0
> Document default_join_distribution_mode query option
> ----------------------------------------------------

> Key: IMPALA-5583
> URL: https://issues.apache.org/jira/browse/IMPALA-5583
> Project: IMPALA
> Issue Type: Sub-task
> Components: Docs
> Affects Versions: Impala 2.9.0
> Reporter: John Russell
> Assignee: John Russell
> Priority: Major
> Fix For: Impala 2.9.0
>
>
> Based on new query option from IMPALA-5381.
> Default setting is:
> {code}
> DEFAULT_JOIN_DISTRIBUTION_MODE: [0]
> {code}
> which I take (also from looking at the gerrit) to mean that 0 = BROADCAST, 1
> = SHUFFLE.
> I presume that it is strictly speaking a numeric argument that could be
> extended to more values in future, as opposed to a Boolean argument that is
> forever restricted to 0 or 1.
