Dmitriy V. Ryaboy commented on PIG-924: --------------------------------------- Regarding deprecation -- I tried setting it back to off, and adding @SuppressWarnings("deprecation") to the shims for 20, but and complained about deprecation nonetheless. Not sure what its deal is. Adding something like this to the main build.xml works. Does this seem like a reasonable solution? {code} <!-- set deprecation off if hadoop version greater or equals 20 --> <target name="set_deprecation"> <condition property="hadoop_is20"> <equals arg1="${hadoop.version}" arg2="20"/> </condition> <antcall target="if_hadoop_is20"/> <antcall target="if_hadoop_not20"/> </target> <target name="if_hadoop_is20" if="hadoop_is20"> <property name="javac.deprecation" value="off" /> </target> <target name="if_hadoop_not20" unless="hadoop_is20"> <property name="javac.deprecation" value="on" /> </target> <target name="init" depends="set_deprecation"> [....] {code} > Make Pig work with multiple versions of Hadoop > ---------------------------------------------- > > Key: PIG-924 > URL: https://issues.apache.org/jira/browse/PIG-924 > Project: Pig > Issue Type: Bug > Reporter: Dmitriy V.

It is possibly to write a dynamic shim that allows Pig to > use the correct calls for any of the above versions of Hadoop.
