Hey hive gurus -

On the wiki I found a section about running Hive jobs in local mode,
however, it uses a separate JVM. Is it possible to run the map reduce jobs
inside the current process? I'm able to attach a debugger to the CLI
process but haven't been able to figure out debugging the MR tasks. Any
tips would be appreciated (and I'll update the wiki).

Thanks!
Travis

you can try to set mapred.job.reuse.jvm.num.tasks to higher value in
mapred-site.xml conf file, this will enable jvm reuse.
