Hi Lefty,
The Hive aggregate functions as you provide just states:
DOUBLE
stddev_pop(col)
Returns the standard deviation of a numeric column in the group.
DOUBLE
stddev_samp(col)
Returns the unbiased sample standard deviation of a numeric column in the group.
There is no mention
Hi Lefty,
ql/src/java/org/apache/hadoop/hive/ql/exec/FunctionRegistry.java:
system.registerGenericUDAF(stddev, new GenericUDAFStd());
ql/src/java/org/apache/hadoop/hive/ql/exec/FunctionRegistry.java:
system.registerGenericUDAF(stddev_pop, new GenericUDAFStd());
I use hive 0.14 the result is

Can you also supply the table's DDL and a few lines of your raw data?

Mich, the linked documentation is for Impala, not Hive. (Perhaps Hive is
the same, I don't know.) But the Hive documentation doesn't explain
much: Built-in
Aggregate Functions (UDAF)
Hi Alan,

Hi Alan,
Hi,
I'm attempting to write a ReaderReader and RecordWriter for ORC that
support reading and writing String for HiveChar and HiveVarchar and
BigDecimal for HiveDecimal to simplify usage a little - I need Serializable
types.
To do this I've gone the ObjectInspector route, eg:
... extends
Hi,
I'm a relatively new user to Hive and was trying to format a column of
String datatype from Uppercase to Camel-case. I could see the INITCAP()
function in the language manual, and also could find related notes on JIRA
stating it is available. But for some reason when I run my query it shows
Available in build 1.1.0

Hi All,
I am new to Hive. Just set up a 5 nodes Hadoop environment and want to have
a try on HiveQL.
Is there any dataset I can download to play HiveQL. The dataset should have
several tables some I can write some complex join. About 100G should be
fine.
Thanks,
Xiaohe
Hi Xiaohe,
If it's data set that you're looking for, you can find wikipedia data dumps
@ http://dumps.wikimedia.org/enwiki/. Also documentation on the dumps @
http://meta.wikimedia.org/wiki/Data_dumps.
Hope this helps..

Thank you Sanjiv. I've reached out to our Infrastructure vendor to check
what build we're on currently and if we can get the 1.1.0 version. But was
just curious to know, is there a way we can see the build version?
Thanks,

I can suggest 3 options
1. you can use JUnit test to test your UDF (e.g. TestGenericUDFLastDay)
2. you can create q file and test your UDF via mvn (look at udf_last_day.q)
mvn clean install -DskipTests -Phadoop-2
cd itest/qtest
mvn test -Dtest=TestCliDriver -Dqfile=udf_last_day.q
Hi,
I'm developing a new UDF.
I want to be able to test the new jar as I develop without having to copy
the Jar up to HDFS every time I change code and recompile the Jar.
I'm using Hive CLI for testing, and adding this command:
add jar 'file:///home/abohr/test/hive-udf-1.0-SNAPSHOT.jar';

You can see the version in two places
