Namit Jain commented on HIVE-3334:
----------------------------------
The following query:
set hive.stats.autogather=false;
-- Create temp, and populate it with some values in src.
CREATE TABLE temp(key STRING, val STRING) STORED AS TEXTFILE;
-- Build an index on temp.
CREATE INDEX temp_index ON TABLE temp(key) as 'COMPACT' WITH DEFERRED REBUILD;
ALTER INDEX temp_index ON temp REBUILD;
SET hive.input.format=org.apache.hadoop.hive.ql.io.HiveInputFormat;
SET hive.optimize.index.filter=true;
SET hive.optimize.index.autoupdate=true;
SET hive.optimize.index.filter.compact.minsize=0;
-- load a file into a table with an index
-- The stats task should follow the index update task
explain
load data local inpath '../data/files/srcbucket20.txt' INTO TABLE temp;
The plan for load is as follows:
STAGE DEPENDENCIES:
Stage-0 is a root stage
Stage-1 depends on stages: Stage-0
Stage-1 depends on stages: Stage-1
Stage-0 depends on stages: Stage-1
null depends on stages: Stage-1
Stage-2 depends on stages: Stage-1
