I thought I was running Hive with those changes merged in, but to make
sure, I built the latest trunk version. The behavior changed somewhat
(as in, it runs 2 stages instead of 1), but it still generates the
same number of files (# of files generated is equal to the number of

Hello,
I'm trying to connect to hive using the JDBC driver in embedded mode. I can
load the driver successfully & connect to it via:
hiveConnection = DriverManager.getConnection( "jdbc:hive://", "", "" )

I see. If you are using dynamic partitions, HIVE-1307 and HIVE-1622 need to be
there for merging to take place. HIVE-1307 was committed to trunk on 08/25 and
HIVE-1622 was committed on 09/13. The simplest way is to update your Hive trunk
and rerun the query. If it still doesn't work maybe you ca

Hi Ning,
For the dataset I'm experimenting with, the total size of the output
is 2mb, and the files are at most a few kb in size. My
hive.input.format was set to default HiveInputFormat; however, when I
set it to CombineHiveInputFormat, it only made the first stage of the
job use fewer mappers. T
The settings looks good. The parameter hive.merge.size.smallfiles.avgsize is
used to determine at run time if a merge should be triggered: if the average
size of the files in the partition is SMALLER than the parameter and there are
more than 1 file, the merge should be scheduled. Can you try to
Thanks Jeff. I'll add something to the JIRA case. I'm after what I think are
fairly common use cases, such as:
create table corporate_expenses(cost_center INT, fiscal_date STRING,
expense_amount DOUBLE);
given tab-delimited file data.txt:
SALES 20101118 3939
As noted here, when writing to HBase, existing rows are overwritten, but old
rows are not deleted.

This is unrelated to Hive/HBase integration; it looks like a Hadoop version

Hi,
Does the INSERT clause have to include the OVERWRITE, which means that the
new data will overwrite the previous data? How to implement the indeed
INSERT operation, instead of OVERWRITE?
BTW: How to implement the DELETE operator? thanks
