- CDPD-48568: JAR storage does not work on AWS S3 for Schema
Registry
-
If you are using AWS S3 to store the serializer and deserializer JAR files used by Schema
Registry, the Schema Registry server might not be able reach these JAR files. As a result,
message serialization and deserialization will not work with the affected schemas. If you are
affected by this issue, class not found errors related to AWS library classes will be present
in the Schema Registry server logs.
-
Ensure that the
aws-java-sdk-bundle-[***VERSION***].jar file is
available in
/opt/cloudera/parcels/CDH/lib/schemaregistry/hadoop-plugin/hadoop-schema-registry-plugin-impl/.
This is the location that contains all the JAR files for the Hadoop plugin classpath.
- Find the aws-java-sdk-bundle-[***VERSION***].jar
file.
The file is located in the folder that contains all common JAR files for parcels.
You can find it using the following
command:
find /opt/cloudera/parcels/CDH/jars -iname '*aws-java-sdk-bundle*.jar
The
output of the command lists multiple versions. Take note of the latest version. For
example:
/opt/cloudera/parcels/CDH/jars/aws-java-sdk-bundle-1.12.316.jar
- Create a symlink in
/opt/cloudera/parcels/CDH/lib/schemaregistry/hadoop-plugin/hadoop-schema-registry-plugin-impl/
that points to the
aws-java-sdk-bundle-[***VERSION***].jar. For example:
ln -s /opt/cloudera/parcels/CDH/jars/aws-java-sdk-bundle-1.12.316.jar /opt/cloudera/parcels/CDH/lib/schemaregistry/hadoop-plugin/hadoop-schema-registry-plugin-impl/aws-java-sdk-bundle-1.12.316.jar
- Restart the Schema Registry service.
