------------------------------------
Summary: Reduce Kafka dependencies in hadoop-kafka module
Key: HADOOP-13681
URL: https://issues.apache.org/jira/browse/HADOOP-13681
Project: Hadoop Common
Issue Type: Improvement
Components: metrics
Affects Versions: 3.0.0-alpha1
Reporter: Grant Henke
The newly added Kafka module defines the Kafka dependency as:
{noformat}
...
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-2.10</artifactId>
<version>${kafka.version}</version>
...
{noformat}
This is unfavorable because its using the server dependency, which transitively
has the client jars. The server dependency includes all of the server code and
some larger transitive dependencies like Scala and Zookeeper.
Instead the pom file should be changed to only depend on the clients jar which
is a much smaller footprint:
{noformat}
...
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>${kafka.version}</version>
...
{noformat}
