How to make a Hive UDF with conflicting Guava
If you're using Hive sooner or later you'll need to create user defined functions (UDFs). Chances are such a function would use a code that depends on the Guava library. And it is not that unlikely that the required Guava version would be newer than Hive's. Then you're running into a trouble. Hopefully this article save you much of the pain I had to suffer to make it working. Let's make a simple U
Hive UDFを自分で追加するときの注意点メモ - たごもりすメモ
メモ。CDH3u2 (hive-0.7.1-cdh3u2) での話。 (1/23 HiveServerについていくつか追記した) Hiveで自分でつくった関数(User Defined Function: UDF)を使いたい！ と思い艱難辛苦を乗り越えJavaのコードを書きjarにまとめたとする。書くまでの話はWikiの該当ページなどを熟読するのがよろしい。 で、じゃあどうやってHive起動時に読み込めばいいの、という話。 add jarコマンド hiveコマンドを起動するマシンの適当なディレクトリにjarファイルを置き、そのディレクトリをカレントディレクトリとしてhiveを起動して以下のコマンドを実行する。 hive> add jar udfclass.jar; hive> create temporary function myfunc as 'my.package.udf.Class

How-to: Include Third-Party Libraries in Your MapReduce Job - Cloudera Blog
“My library is in the classpath but I still get a Class Not Found exception in a MapReduce job” – If you have this problem this blog is for you. Java requires third-party and user-defined classes to be on the command line’s “–classpath” option when the JVM is launched. The `hadoop` wrapper shell script does exactly this for you by building the classpath from the core libraries located in /usr/lib/
Making Really Executable Jars
Making Really Executable Jars 20 Jun 2011 One of the more annoying things about writing command line applications in Java is that the Java model of an executable is the so called executable jar, which is executed via an incantation like There has long been a hack known in some circles, but not widely known, to make jars really executable, in the chmod +x sense. The hack takes advantage of the fact
