Subject [jira] Commented: (MAPREDUCE-972) distcp can timeout during rename operation to s3

Aaron Kimball commented on MAPREDUCE-972:
-----------------------------------------

That Hadoop QA output seems a bit confused; it's a failing build applying MAPREDUCE-973. Can
anyone explain what's up there?

> rename() in S3 is implemented as copy + delete. The S3 copy operation can perform very
slowly, which may cause task timeout.
