---------------------------------------
Summary: Hadoop: automatically define best "partially raw"
comparator based on key type.
Key: IGNITE-4461
URL: https://issues.apache.org/jira/browse/IGNITE-4461
Project: Ignite
Issue Type: Task
Components: hadoop
Affects Versions: 1.8
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Fix For: 2.0
We have special {{PartiallyRawComparator}} interface which provides nice
speedup by removing unnecessary objects deserializations during insert into
result multi-map. And we have a one implementation for now for {{Text}} class:
{{TextPartiallyRawComparator}}.
We should do the following:
1) Try guessing proper comparator in runtime using
{{JobConf.getOutputKeyClass()}} property.
2) Add ability to disable this automatic resolution.
