I would recommend that you try Rank function with columns from just one
table first.
Once it is established that rank is working fine then add all the joins.
I am still on Hive 0.10 so cannot test it myself.
However, I can find a similar issue on following link - so its possible you
are
Hi All,
I have installed hive 4 months back, i don't have any database installed in
my system. till today it was working fine, but now i'm getting this
metadata error... can anyone please suggest me do i have to create any
settings for derby database to avoid this error??
error is like
As the error message states: One ore more arguments are expected, you
have to pass a column to the rank function.

Jerome has already passed column - mag.co_societe for rank.
syntax - RANK() OVER (PARTITION BY mag.co_societe ORDER BY
mag.me_vente_ht)
This will generate a rank for column mag.co_societe based on column value
me_vente_ht
Jerome,
Its possible you are also hitting the same bug as I
Hi Richa,
I have tried one query, with what i've understand of Vijay's tips.
SELECT code_entite, RANK(mag.me_vente_ht) OVER (PARTITION BY mag.co_societe
ORDER BY mag.me_vente_ht) AS rank FROM default.thm_renta_rgrp_produits_n_1
mag;
This query is working, it gives me results.

Hi,
There are many online tutorials and blogs to provide quick get-set-go sort of
information. To start with you can learn Hadoop. For detailed knowledge you
will have to go through e-books as mentioned by Lefty.
These books are bulky but will provide every bit of hadoop.
I recently came
Please let me knw which approach is better. Either i save my data directly
to HDFS and run hive (shark) queries over it OR store my data in HBASE, and
then query it.. as i want to ensure efficient data retrieval and data
remains safe and can easily recover if hadoop crashes.

what's the purpose of data storage?
whats the read and write throughput you expect?
whats the way you will access data while read?
whats are your SLAs on both read and write?
there will be more questions others will ask so be ready for that :)

I use data to generates reports on daily basis, Do couple of analysis and
its insert once and read many on daily basis. But My main purpose is to
secure my data and easily recover it even if my hadoop(datanode) OR HDFS
crashes. As uptill now, i'm using approach in which data has been retrieved
Hello ma'm,
Apologies first of all for responding so late. Stuck with some urgent
deliverables. Was out of touch for a while.

Hi Tariq,
No Problems,
It was the hive.jar.path property that was not being set. Figured it out and
fixed it.
Got the plan.xml and jobconf.xml now will debug hadoop to get the rest of info.
Thanks,
Warm regards,
Bharati

Hey all -
I was wondering if there were any shortcut Java courses out there. As
in, I am not looking for a holistic learn everything about Java course, but
more of a So you are a big data/hive geek and you get Python/Perl pretty
well, but when you try to understand Java your head explodes and it
The Data Science course on Coursera has a pretty good overview of map
reduce, Hive, and Pig without going into the Java side of things.
https://www.coursera.org/course/datasci. It's not in depth, but it is
enough to get started.

Ha. I have the same problem. It is hard to find resources aimed at the
right level. I have been pretty happy with the book Head First Java by
Kathy Sierra and Bert someone er other.

Hello,
I have just started using Hive and I was trying to create an external table
with the csv file placed in NFS. I tried using file:// and local://. Both
of these attempts failed with the error:
create external table outside_supplier (S_SUPPKEY INT, S_NAME STRING,
S_ADDRESS STRING,
Hey Saurabh,
I tried this command and it still gives the same error. Actually the folder
name is supplier and supplier.tbl is the csv which resided inside it. I had
it correct in the query but in mail it is wrong. So the query that I
executed was:
create external table outside_supplier
Hi,
I'm running a query like this:

)
FROM bar;
On a small enough dataset that works fine but when switching to a
larger sample we're seeing exceptions like this:

Hi,
Currently, I'm executing the following steps(Hadoop 1.1.2, Hive 0.11 and
Sqoop-1.4.3.bin__hadoop-1.0.0) :
1.Import data from MySQL to Hive using Sqoop
2.Execute a query in Hive and store its output in a Hive table
3.Export the output to MySQL using Sqoop
I was wondering if
The short answer is no. You could at the moment write your own input
format/output format in order to do so. I don't know all the details for
hive but that's possible. However, you will likely run a DOS against your
database if you are not careful. Hive could embed sqoop in order do that
smartly
I read of the term 'JDBC Storage Handler' at
https://issues.apache.org/jira/browse/HIVE-1555
The issues seems open but I just want to confirm that it has not been
implemented in the latest Hive releases.
