Review request for Tajo.
Bugs: TAJO-356
https://issues.apache.org/jira/browse/TAJO-356
Repository: tajo
Description
-------
Currently, TajoClient cannot deal with simple queries (e.g., select * from
table limit 1 or select 1) which are executed in TajoMaster without distributed
execution. The final results are always stored in HDFS, and TajoClient gets the
result via scanner with TableDesc obtained from GetQueryResultResponse.
For simple queries directly executed at TajoMaster, TajoClient needs to
directly get some binary serialized rows results from GetQueryStatusResponse or
GetQueryResultResponse instead of reading materialized tables.
This feature would be also useful for low latency queries, EXPLAIN clauses and
expr-only statements without FROM clause.
