--------------------------------
Summary: FsShell put using WebHdfsFileSystem goes OOM when file
size is big
Key: HDFS-3696
URL: https://issues.apache.org/jira/browse/HDFS-3696
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.0.0-alpha
Reporter: Kihwal Lee
Priority: Critical
Fix For: 0.23.3, 3.0.0, 2.2.0-alpha
When dong "fs -put" to a WebHdfsFileSystem (webhdfs://), the FsShell goes OOM
if the file size is large. When I tested, 20MB files were fine, but 200MB
didn't work.
I also tried reading a large file by issuing "-cat" and piping to a slow sink
in order to force buffering. The read path didn't have this problem. The memory
consumption stayed the same regardless of progress.
