I'm using Hive 0.12.0 and I've created a partitioned table.
Then I try to insert the data into the table: LOAD DATA LOCAL INPATH 'path/data' insert into table test partition (idx=1)
But then I get the following error:
ERROR metastore.RetryingHMSHandler (RetryingHMSHandler.java:invoke(134)) - NoSuchObjectException(message:partition values=[1])

What's the solution for this?
You need to either pre-generate via add partition the partitions or use dynamic partitions.
Pre-generate partitions:
ALTER TABLE table_name ADD PARTITION (partCol = 'value1') location 'loc1';
Using dynamic partitions:
Dynamic partitions

I am unable to create table with constraints just like primary key or not null. Without constraints I can create table sucessfully.
I found that Hive support primary keys/foreign keys constraint as part of create table command in 2.1.0 and my version is 2.3.0. Following is the example code:
create table test3(a int primary key)
and this returns me the following error message:

I am using Hive 2.3.0 and Hadoop 2.7.3.
You will have to create the PRIMARY KEY using the below command
CREATE TABLE TEST3(A INT
PRIMARY KEY(A) disable novalidate);
Since these constraints are not validated, an upstream system needs to ensure data integrity before it is loaded into Hive.
I have a hive table stored as ORC having a bigint column col1 and many other columns.
Few records of col1 :
3180231637038089849
3185739118697487865
3196698142218730052
3262542509863274723
3180231637038089849
3262542509863274723
3180231637038089849
I need to calculate sum of col1 values. As the sum will be greater than the max value, So I am casting it to decimal(38,0)
select sum(cast(col1 as decimal (38,0))) from sample_table;

I am able to run same query successfully on ubuntu.
Is it mandatory to surround coulmn names with ` in hive2?
date is a reserved word and should be qualified.
You are using the wrong qualifiers. You should use ' and not ‘ or ’.
You have space in the beginning of your location /hive/data...

I created Hive custom UDTF. My new UDTF returns new 3 columns based on input 2 columns.
But, I can't any INSERT operation by using generated values.
For example,
INSERT OVERWRITE DIRECTORY 'generated_data.csv' SELECT udtf(one, two) FROM table_orig;
INSERT OVERWRITE TABLE test_table SELECT udtf(one, two) FROM table_orig;
Both of INSERT queries returns NullPointerException like following:

I am unable to create the partition into a new table from the table which is already present on hive.

After I browsed and found that namenode,datanode folders needs to be deleted and namenode should be formatted.I have done that sanitary task as well.But still the same error I am getting.
Also I have set the replication factor to 1 and all the Hadoop processes are running well.
Please suggest me how to proceed in order to get away from this issue.Your suggestions are much appreciated.
first you need to create
1. table with all field
2. load data into table
3. create table with partition column with their type
4. copy data from first table to partition table
I think the dynamic partition needs to be enabled. following works.
set hive.exec.dynamic.partition.mode=nonstrict;
create table parttable (id int) partitioned by (partcolumn string)
row format delimited fields terminated by '\t'
lines terminated by '\n'
;
create table source_table (id int,partcolumn string)
row format delimited fields terminated by '\t'
lines terminated by '\n'
;
insert into source_table values (1,'Chicago');
insert into source_table values (2,'Chicago');
insert into source_table values (3,'Orlando');
set hive.exec.dynamic.partition=true;
insert overwrite table parttable partition(partcolumn)
select id,partcolumn from source_table;
