Description

In map-reduce action, when specify file, archives element, JavaActionExccutor add it to distributed cache for configuration of launcher.

It cause slow launching mr job.

In fact, all most launcher does not need file , archives. launcher need to inputformat/outputformat class and its dependency.

I make a proposal below feature.

• add property oozie.launcher.distributed.cache.filter=*.jar,*.properties. default is *

• when configure launcher, filter cache files.
