[Hadoop-common-dev] [jira] Created: (HADOOP-1866) distcp requires large heapsize when copying many files

distcp requires large heapsize when copying many files
------------------------------------------------------

Key: HADOOP-1866
URL: https://issues.apache.org/jira/browse/HADOOP-1866
Project: Hadoop
Issue Type: Bug
Components: util
Reporter: Koji Noguchi
Priority: Minor

Trying to distcp 1.5 million files with 1G client heapsize, failed with outofmemory.
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit
exceeded

It would be nice if distcp doesn't require gigs of heapsize when copying large amount of files.
