I have a hive table partitioned by dates. It contains ecomm data in the
format siteid,sitecatid,catid,subcatgid,pid,pname,pprice,pmrp,pdesc
What I need to do is to run a query on table above in hive for top 10
products(count wise) in each sub category. What adds a bit more complexity
is
may be you can share your table ddl, your query and what output r u looking
for

Hi Nitin,
The ddl is as follows:
CREATE EXTERNAL TABLE user_logs(
users_iduuidstring,
siteid int,
site_catid int,
stext string,
catgint, // CATEGORY
scatg int, // SUBCATEGORY
catgnamestring,
scatgname string,
brand string,// PRODUCT BRAND NAME
prrange
will it be a good idea to just get top 10 ranked products by whatever your
ranking is based on and then join it with its metadata (self join or any
other way) ?

hello,
i may need your help with one query. Its always ending with reducucer
timeout in YARN.
I tried increase timeout to 30min but its still not enough and progress is
not moving at all.
Here is query:
INSERT INTO TABLE TMP2
SELECT a.rn
,MAX( a.date_report_end) over ( PARTITION BY a.field1
I think you need to separate out the logic that does your group by
aggregations from the logic of then retrieving all of the other columns for
a single row from that set.
Something like:
select
tbl.myKeyColumn1,
tbl.myKeyColumn2,
tbl.otherValueColumn1,
This hanging issue has been seen when there is a mismatch between the
auth modes of HS2 server and client (usually SASL vs NOSASL).

Hi hive.
I cant run JDBC queries against HiveServer2. It appears the client is
