-----------------------------------------
Hi Bill Wailliam,
Can you give exact scenario. I have tried with below queries on master it is
working fine.
{code}
drop table sample1;
create table sample1(a STRING, b int) partitioned by (partitionid string) ROW
FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE;
LOAD DATA LOCAL INPATH '/home/chinna/install/data/file1.txt' INTO TABLE sample1
partition (partitionid = "one");
drop table sample2;
create table sample2(a STRING, b int) partitioned by (partitionid string) ROW
FORMAT DELIMITED FIELDS TERMINATED BY ',' STORED AS TEXTFILE;
LOAD DATA LOCAL INPATH '/home/chinna/install/data/file2.txt' INTO TABLE sample2
partition (partitionid = "one");
INSERT OVERWRITE TABLE sample2 PARTITION (partitionid = 'one') select a,b from
sample1;
{code}
