Sorry, sent too fast ... either way you do it, you'll need to include all
of the dependencies of the Hive JDBC driver classes in a single JAR and the
apply the shading the unified JAR file. This ensures that all classes that
depend on Thrift 0.9 get updated to use the shaded package. For example,
I'm working with the HCatalog Pig Adapter so I built a single JAR made up
of:
antlr-runtime-3.4.jar commons-io-2.4.jar hive-beeline-0.11.0.jar
hive-serde-0.11.0.jar jdo2-api-2.3-ec.jar protobuf-java-2.4.1.jar
avro-1.7.1.jar commons-lang-2.4.jar hive-cli-0.11.0.jar
hive-service-0.11.0.jar jetty-6.1.26.jar
servlet-api-2.5-20081211.jar
avro-mapred-1.7.1.jar commons-logging-1.0.4.jar hive-common-0.11.0.jar
hive-shims-0.11.0.jar jetty-util-6.1.26.jar slf4j-api-1.6.1.jar
commons-cli-1.2.jar commons-logging-api-1.0.4.jar hive-contrib-0.11.0.jar
jackson-core-asl-1.8.8.jar jline-0.9.94.jar
slf4j-log4j12-1.6.1.jar
commons-codec-1.4.jar commons-pool-1.5.4.jar hive-exec-0.11.0.jar
jackson-jaxrs-1.8.8.jar json-20090211.jar snappy-0.2.jar
commons-collections-3.2.1.jar derby-10.4.2.0.jar hive-hbase-handler-0.11.0.jar
jackson-mapper-asl-1.8.8.jar libfb303-0.9.0.jar ST4-4.0.4.jar
commons-compress-1.4.1.jar guava-11.0.2.jar hive-hwi-0.11.0.jar
jackson-xc-1.8.8.jar libthrift-0.9.0.jar tempus-fugit-1.1.jar
commons-configuration-1.6.jar hcatalog-core-0.11.0.jar hive-jdbc-0.11.0.jar
JavaEWAH-0.3.2.jar log4j-1.2.16.jar xz-1.0.jar
commons-dbcp-1.4.jar hcatalog-pig-adapter-0.11.0.jar
hive-metastore-0.11.0.jar
javolution-5.5.1.jar metrics-core-2.1.2.jar zookeeper-3.4.3.jar
Any class in any of these JAR files that depend on Thrift 0.9 classes will
get updated at the bytecode level to refer to my shaded package -
org.shaded.thrift
Make sense?
