Todd Lipcon commented on HADOOP-6762: ------------------------------------- Either way seems cool. I've never seen call param serialization be a bottleneck where parallelization would really help. Whichever one makes the code cleaner :) > exception while doing RPC I/O closes channel > -------------------------------------------- > > Key: HADOOP-6762 > URL: https://issues.apache.org/jira/browse/HADOOP-6762 > Project: Hadoop Common > Issue Type: Bug > Affects Versions: 0.20.2 > Reporter: sam rash > Assignee: sam rash > Attachments: hadoop-6762-1.txt, hadoop-6762-2.txt, hadoop-6762-3.txt, > hadoop-6762-4.txt, hadoop-6762-6.txt > > > If a single process creates two unique fileSystems to the same NN using > FileSystem.newInstance(), and one of them issues a close(), the leasechecker > thread is interrupted.
