Re: is that possible to use Hive 0.11 with libthrift 0.7
Hi Zhang,

I have the same issue in that I use some Cassandra client API's that depend
on Thrift 0.7 and HCatalog 0.11 that depends on Thrift 0.9. I opted for
using the jarjar utility to "shade" the thrift 0.9 classes. Here's what I
added to the build.xml file for the hcatalog-pig-adapter project:

<target name="jarjar">
    <echo message="basedir=${basedir}"/>
    <copy file="${basedir}/../core/build/hcatalog-core-0.11.0.jar"
    <copy file="${basedir}/build/hcatalog-pig-adapter-0.11.0.jar"
    <copy todir="${basedir}/deps">
      <fileset dir="${basedir}/../../build/dist/lib" includes="hive-*.jar"/>
    <taskdef name="jarjar" classname="com.tonicsystems.jarjar.JarJarTask"
    <jarjar jarfile="hcat-pig-shaded.jar">
        <zipgroupfileset dir="deps" includes="*.jar"/>
        <rule pattern="org.apache.thrift.**" result="org.shaded.thrift.@1"/>

I basically cooked up a deps directory that contains all the JARs that the
hcatalog-pig-adapter depends on and then used jarjar to create a single jar
with the thrift classes renamed at the bytecode level to org.shaded.thrift

You can do something similar for the JDBC code.
