shahrs87 edited a comment on issue #509: HBASE-22877 WebHDFS based export snapshot will fail if hfile is in archive directory URL: https://github.com/apache/hbase/pull/509#issuecomment-525039584 > But in hadoop 2.x, this problem do exists; This bug **does not** exist in branch-2.6.0 also. Here is the git repo for branch-2.6.0 https://github.com/apache/hadoop/tree/branch-2.6.0 Refer to WebHdfsFileSystem#open --> OffsetUrlInputStream(UnresolvedUrlOpener o, OffsetUrlOpener r) --> ByteRangeInputStream(URLOpener o, URLOpener r) --> ByteRangeInputStream#getInputStream() --> ByteRangeInputStream#openInputStream() --> UnresolvedUrlOpener#connect() --> AbstractRunner#run() --> AbstractRunner#runWithRetry() method which in turn calls NameNodeWebHdfsMethods on server side and it will throw FileNotFoundException wrapped in RemoteException. One suggestion: Please enable trace logging on client side if possible. It will show you many debug and trace level logs about communication between client and server to understand WebHdfsFileSystem better. @VicoWu Hope this helps.
