-------------------------------------
Summary: Failure of one mapper should not affect other mappers in
MR index build
Key: PHOENIX-2154
URL: https://issues.apache.org/jira/browse/PHOENIX-2154
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
Once a mapper in the MR index job succeeds, it should not need to be re-done in
the event of the failure of one of the other mappers. The initial population of
an index is based on a snapshot in time, so new rows getting *after* the index
build has started and/or failed do not impact it.
Also, there's a 1:1 correspondence between index rows and table rows, so
there's really no need to dedup. However, the index rows will have a different
row key than the data table, so I'm not sure how the HFiles are split. Will
they potentially overlap and is this an issue?
