Hive 0.14 UDF Maven Project Missing Dependencies - maven

Question

I was trying to set up a Maven project that will contain user defined functions (UDFs) that I'd like to use in my Hive queries. I started with a Maven project containing no source files, and the following POM:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>exp</groupId>
<artifactId>HiveUdfTestProject</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.hive</groupId>
<artifactId>hive-exec</artifactId>
<version>0.14.0</version>
</dependency>
</dependencies>
</project>
When I tried to build the project, I get the following error:
Failed to execute goal on project HiveUdfTestProject: Could not
resolve dependencies for project
exp:HiveUdfTestProject:jar:1.0-SNAPSHOT: The following artifacts could
not be resolved:
org.apache.calcite:calcite-core:jar:0.9.2-incubating-SNAPSHOT,
org.apache.calcite:calcite-avatica:jar:0.9.2-incubating-SNAPSHOT:
Could not find artifact
org.apache.calcite:calcite-core:jar:0.9.2-incubating-SNAPSHOT -> [Help

Answer 1

I found the calcite-core-incubating jar in the maven central repository (but not the incubating-snapshot version) required by the hive-exec 0.14.0 dependency.
Adding the calcite-core from maven central got rid of the original error, and introduced a new missing dependency "pentaho-aggdesigner-algorithm" which I found on ConJars.
Adding the conjars repo and the pentaho dependency made a new missing dependency appear "org.apache.calcite:calcite-avatica:jar:0.9.2-incubating-SNAPSHOT" whose incubating (but not snapshot) dependency was available in the maven central repo.
Adding the calcite-avatica dependency to the POM made the empty project build successfully at last.
Here is the final POM needed to make a project intended for Hive UDFs build:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>exp</groupId>
<artifactId>HiveUdfTestProject</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
</properties>
<repositories>
<repository>
<id>conjars.org</id>
<url>http://conjars.org/repo</url>
</repository>
</repositories>
<dependencies>
<!-- From Maven Central -->
<dependency>
<groupId>org.apache.hive</groupId>
<artifactId>hive-exec</artifactId>
<version>0.14.0</version>
</dependency>
<dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-core</artifactId>
<version>0.9.2-incubating</version>
</dependency>
<dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-avatica</artifactId>
<version>0.9.2-incubating</version>
</dependency>
<!-- From conjars -->
<dependency>
<groupId>org.pentaho</groupId>
<artifactId>pentaho-aggdesigner-algorithm</artifactId>
<version>5.1.3-jhyde</version>
</dependency>
</dependencies>
</project>
Once the empty project built, I tried integrating the POM settings into a larger existing Maven project and saw errors about calcite-core specifically looking for the snapshot version. To get past this, I changed the hive-exec dependency to look like this:
<dependency>
<groupId>org.apache.hive</groupId>
<artifactId>hive-exec</artifactId>
<version>0.14.0</version>
<exclusions>
<exclusion>
<groupId>org.apache.calcite</groupId>
<artifactId>*</artifactId>
</exclusion>
</exclusions>
</dependency>

Answer 2

I explicitly included the calcite-core and calcite-avatica projects as dependencies, and my project (which also includes the Hive 14 dependencies), no longer failed with the 'artifacts could not be resolved error'
<dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-core</artifactId>
<version>1.0.0-incubating</version>
</dependency>
<dependency>
<groupId>org.apache.calcite</groupId>
<artifactId>calcite-avatica</artifactId>
<version>1.0.0-incubating</version>
</dependency>
From what I can tell, this is an open issue with Hive 14. See https://issues.apache.org/jira/browse/HIVE-8906 for more info.

I've resolved the same issue by adding below dependencies to /ql/pom.xml
org.pentaho
pentaho-aggdesigner-algorithm
5.1.3-jhyde
<dependency>
<groupId>eigenbase</groupId>
<artifactId>eigenbase-properties</artifactId>
<version>1.1.4</version>
</dependency>
<dependency>
<groupId>net.hydromatic</groupId>
<artifactId>linq4j</artifactId>
<version>0.4</version>
</dependency>
and below repository to /pom.xml under positories
<repository>
