Summary: Unused Logger in
org.apache.hadoop.hive.ql.udf.generic.GenericUDAFCount
Key: HIVE-11136
URL: https://issues.apache.org/jira/browse/HIVE-11136
Project: Hive
Issue Type: Improvement
Reporter: Nishant Kelkar
Priority: Trivial
There is an unused logger in the GenericUDAFCount. We could either try/catch
all the code that throws exceptions and log them, or get rid of the logger.
Relevant section of code:
{code}
public class GenericUDAFCount implements GenericUDAFResolver2 {
private static final Log LOG =
LogFactory.getLog(GenericUDAFCount.class.getName());
{code}

[jira] [Created] (HIVE-11114) Documentation of Pentaho Missing from Maven Central
Nishant Kelkar created HIVE-4: - Summary: Documentation of Pentaho Missing from Maven Central Key: HIVE-4 URL: https://issues.apache.org/jira/browse/HIVE-4 Project: Hive Issue Type: Task Reporter: Nishant Kelkar Assignee: Nishant Kelkar Priority: Minor I recently cloned the Hive Git repository. When I went into the hive/ql sub-project and issued the command 'mvn clean compile -Phadoop-1', I got the following build error: [ERROR] Failed to execute goal on project hive-exec: Could not resolve dependencies for project org.apache.hive:hive-exec:jar:2.0.0-SNAPSHOT: Could not find artifact org.pentaho:pentaho-aggdesigner-algorithm:jar:5.1.5-jhyde in US (http://repo.maven.apache.org/maven2) -> [Help 1] This is because the pentaho-aggdesigner-algorithm dependency is not supported by Maven central; however, it is supported by Conjars. As a quick fix, I downloaded the jar from Conjars repo, and manually installed this dependency to my local Maven by following the instructions here: http://www.mkyong.com/maven/how-to-include-library-manully-into-maven-local-repository/ However, I feel this dependency should be supported on Maven central (I'm not sure where to create this ticket/whom with, but Hive is my use case, so any pointers greatly appreciated). This ticket tracks the task of documenting this fact on the Hive wiki as an additional Note. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
[jira] [Commented] (HIVE-8642) Hive stack() UDTF Doesn't Support NULL Insert Values

Thanks [~navis]! This solves my problem.
However, I feel that queries of the form "INSERT INTO TABLE table_a SELECT
UDTF(args) AS (arg_names) FROM table_b" should have support for null field
insertions. This is because the output of the UDTF is tightly coupled with the
schema of table_a. Right now, debugging through the code showed that null
arguments to a UDTF generate VoidObjectInspector as input to the initialize()
method (which they shouldn't, since the schema of table_a should be sufficient
information to get correct ObjectInspectors).
Please correct me if I'm wrong (I've only started digging into Hive source
code). Thoughts?
