Subject Re: FileSystem Closed.
Date Thu, 26 Jul 2012 12:21:05 GMT
Thank you

I've been researching based on your opinions, and found the below two
solutions.
These are the answers for who has FileSystem.closed issue like me.


 -  close it in your cleanup method and you have JVM reuse turned on
    (mapred.job.reuse.jvm.num.tasks)

 - set "fs.hdfs.impl.disable,cache' to turn in the conf, and new instances
don't get cached.


Do you think they will work on my problem?
