For example during the distcp I just ran the setup phase took 15 minutes and the actual copy 3 minutes. Could this be improved? Or at least a progress bar added so the user doesn't think it stalled. > I also often see exceptions like this in the setup, but the distcp finishes eventually. > java.io.EOFException > at java.io.DataInputStream.readShort(DataInputStream.java:298) > at org.apache.hadoop.dfs.DFSClient$DFSOutputStream.endBlock(DFSClient.java:1672) > at org.apache.hadoop.dfs.DFSClient$DFSOutputStream.close(DFSClient.java:1744) > at org.apache.hadoop.fs.FSDataOutputStream$PositionCache.close(FSDataOutputStream.java:49) > at org.apache.hadoop.fs.FSDataOutputStream.close(FSDataOutputStream.java:64) > at org.apache.hadoop.io.SequenceFile$Writer.close(SequenceFile.java:774) > at org.apache.hadoop.util.CopyFiles$FSCopyFilesMapper.setup(CopyFiles.java:351) > at org.apache.hadoop.util.CopyFiles.copy(CopyFiles.java:773) > at org.apache.hadoop.util.CopyFiles.run(CopyFiles.java:854) > at org.apache.hadoop.util.ToolBase.doMain(ToolBase.java:187) > at org.apache.hadoop.util.CopyFiles.main(CopyFiles.java:864) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
