You should provide more information in order to get proper support such as the
exact command you used to create the table.

Use a regexserde to split the text in words. There's documentation on the hive
wiki.
But it might be better to use a script. See the post by Shouguo Li earlier on
this mailing list.
After all, when you use a Python script, for example, you could use the Natural
Language Processing Toolkit to ge
You could try to remove the first line of a file before passing it on to hive.
Something like `sed -i '1d' filename`.

Hi,
I have a table created with
CREATE TABLE raw(partition1 string, partition2 string, data string) ROW FORMAT
DELIMITED FIELDS TERMINATED BY '\001' STORED AS TEXTFILE;
I want to further process "data" and put it in a partition (partition1,
partition2) defined by the values in the relevant row
Should be here:
./conf/hive-exec-log4j.properties
./conf/hive-log4j.properties

Do you have the syntax for the proper hive QL command?
Thanks!

Is it possible to load data into a hive table that is fed in using a unix pipe
or streamed via a script? I've only seen streaming options when using SELECT
TRANSFORM.
Thanks in advance,

Does anyone know the proper documentation for using the "CREATE INDEX" command
in hive? The hive homepage doesn't have the information.

I figured it out. A jar is missing.
./src/build/contrib/hive-contrib-0.7.1.jar
If you don't see this jar, you need to go into src and run `ant` to build the
extra jars.
Then, you can do:
DROP TABLE serde_regex;
add jar ./src/build/contrib/hive-contrib-0.7.1.jar;
create the table, load the data
I can replicate it using this example. A
SELECT * FROM serde_regex;
works, but
SELECT host FROM serde_regex;
doesn't:
hive> SELECT host FROM serde_regex;
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks is set to 0 since there's no reduce operator
Starting Job = job_201109
Hi,
I'm very new to Hadoop+Hive. I've worked through the Hadoop in Action book and
understand the basic principles. However, I've had a hard time finding
information on loading xml data into a hive table. CSV and TSV are
straightforward, but for XML it seems you either need to write some custom
20 matches
