currently, i have my main jar and then 2 depedent jars. what i do is
1. copy dependent-1.jar to $HADOOP/lib
2. copy dependent-2.jar to $HADOOP/lib
then, when i need to run my job, MyJob inside main.jar, i do the following.
hadoop jar main.jar demo.MyJob -libjars dependent-1.jar,dependent-2.jar
-Dmapred.input.dir=/input/path -Dmapred.output.dir=/output/path
what i want to do is NOT copy the dependent jars to $HADOOP/lib and always
specify -libjars. is there any way around this multi-step procedure? i
really do not want to clutter $HADOOP/lib or specify a comma-delimited list
of jars for -libjars.
any help is appreciated.
Hello,
Specify the full path to the jar on the -libjars? My experience with
-libjars is that it didn't work as advertised.
Search for an older post on the list about this issue ( -libjars not
working). I tried adding a lot of jars and some got on the job classpath
(2), some didn't (most of them).
I got over this by including all the jars in a lib directory inside the
main jar.
Cheers,
