Thanks for commenting out. Yes I figured that out, its a UDF. So now I have
created a new UDF Rank and added to classpath also. But when I am again
running the below query-
SELECT buyer_id, item_id, created_time
FROM (
SELECT buyer_id, item_id, Rank(buyer_id) as rk, created_time
FROM testi
hive does not support update as a query
its a costly operation to update records in hive
as a hadoop based system mainly its meant like write once read many times

Hi All,
Is it possible to insert and/or update some data in a hive table not
through any local file?
To be specific, I look to insert and update some data (not large amount)
to a hive table through queries (like insert into...) in a traditional SQL
style, where you specify the new data in the
hive has no built-in rank function. you'd need to use a user-defined
function (UDF) to simulate it. there are a few custom implementations
on the net that you can leverage.

This is my below requirement. I need- *Find `TOP 10` data for each
`BUYER_ID, *So I cannot use LIMIT 10 here in this case.
This is the below table
CREATE TABLE IF NOT EXISTS TestingTable1
(
BUYER_ID BIGINT,
ITEM_ID BIGINT,
CREATED_TIME STRING
)
And this is the below data
hello, you can use "desc" and "limit 10" to filter the top 10.

yes you need an input format. I have one that turns key plus value to a
pairwritable

Thanks Navis.
The problem is that the key and value are custom classes. e.g, key is class
A, and value is class B. we want to show certain data in Class A and B from
getters. so we do need a SerDe to deserialize the data.
Since SerDe interface can only pass one parameter, so I need to write a
Inp
Yup that worked for me. I figure that out after reading the docs, INNER
JOIN means JOIN in HiveQL.

You can try 'STORED AS SEQUENCEFILE' when creating table.

Hi all,
New to here. I have sequence files and I want to read in Hive, I did some
search on the net. looks the way I need to do
1. Write new FileInputFormat so Hive can read both key and value.

2. Write a SerDe to deseriali
Did you try just using "join" instead of "inner join"?

I wrote this query but everytime I get the below error.
select * from (select t2.buyer_id, t2.item_id, t2.created_time as
created_time, subq.user_id, subq.product_id, subq.timestamps as timestamps
from

No, there is no way to re-attach. Because hive works with
side-directories and moves data at the last step the job is not
salvageable. Your should kill the job from the hadoop job tracker.

Hi all -
I've just had a hive CLI process die wile a job was running. Even
though the CLI has terminated, the hadoop job is still being
processed. Is there any way to either:
a) reattach the hive command to an already-running job, or
b) read the query results out of HDFS when the job actually fi
