[jira] [Updated] (TEZ-4304) Enable per-vertex configuration of
split grouping
[ https://issues.apache.org/jira/browse/TEZ-4304?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
László Bodor updated TEZ-4304:
------------------------------
Description:
Idea is to have options like:
{code}
tez.grouping.split-count.Map1
tez.grouping.by-length.Map1
tez.grouping.by-count.Map1
tez.grouping.max-size.Map1
tez.grouping.min-size.Map1
{code}
I'm wondering what benefit can above options have in case of complicated, multistage queries, where we want to modify split grouping behavior only for one vertex.
