Akira Ajisaka commented on HDFS-10778: -------------------------------------- Thanks [~linyiqun] for updating the patch! bq. The option '-h' is already used for -help in hdfs oiv command. So it seems we would the other option, now I use a new option -format to instead of that. Agreed. bq. I found another bug when I tested the new option in class OfflineImageViewer, it is missing the following code in method OfflineImageViewer#buildOptions: Nice catch. Would you file another jira for this issue and split the patch? The bug is similar to HDFS-5866. > Optimize the output result of FileDistribution processor in hdfs oiv command > ---------------------------------------------------------------------------- > > Key: HDFS-10778 > URL: https://issues.apache.org/jira/browse/HDFS-10778 > Project: Hadoop HDFS > Issue Type: Improvement > Components: tools > Affects Versions: 2.7.1 > Reporter: Yiqun Lin > Assignee: Yiqun Lin > Priority: Minor > Attachments: HDFS-10778.001.patch, HDFS-10778.002.patch > > > Now It's not directly to understand the output result of the > {{FileDistribution}} processor that in hdfs oiv command for users.
