Conflict between iotdb-session and hive-jdbc

[haowdev]

Experts,

We have a maven project with following dependencies in pom.xml.

<dependency>
        <groupId>org.apache.iotdb</groupId>
        <artifactId>iotdb-session</artifactId>
        <version>0.12.1</version>
    </dependency>
   <dependency>
            <groupId>org.apache.hive</groupId>
            <artifactId>hive-jdbc</artifactId>
            <version>1.1.0</version>
   </dependency>
   <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-common</artifactId>
            <version>2.7.3</version>
   </dependency>

With only adding the dependency of "iotdb-session". the code works well that I can query data from iotdb.

<dependency>
        <groupId>org.apache.iotdb</groupId>
        <artifactId>iotdb-session</artifactId>
        <version>0.12.1</version>
    </dependency>

However, exception happened when I add following dependencies.

   <dependency>
            <groupId>org.apache.hive</groupId>
            <artifactId>hive-jdbc</artifactId>
            <version>1.1.0</version>
   </dependency>
   <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-common</artifactId>
            <version>2.7.3</version>
   </dependency>

Any update on this incompatible issue?

This is due to thrift dependency conflict between iotdb-session and hive.

Try to use mvn dependency:tree to see which dependency conflicts with iotdb-session.

Then, use to remove the dependency

<dependency>
            <groupId>org.apache.hive</groupId>
            <artifactId>hive-jdbc</artifactId>
            <version>1.1.0</version>
            <exclusions>
                <exclusion>
                    <groupId>org.apache.thrift</groupId>
                    <artifactId>libthrift</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
