Bob commented on HDFS-247: -------------------------- Hi [~Pooja.Gupta], I am interesting at this feature, could you share you idea on it or any status updates? Thanks. > A tool to plot the locations of the blocks of a directory > --------------------------------------------------------- > > Key: HDFS-247 > URL: https://issues.apache.org/jira/browse/HDFS-247 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Owen O'Malley > Assignee: Pooja Gupta > Labels: newbie > > It would be very useful to have a command that we could give a hdfs directory > to, that would use fsck to find the block locations of the data files in that > directory and group them by host and display the distribution graphically. We > did this by hand and it was very for finding a skewed distribution that was > causing performance problems. The tool should also be able to group by rack > id and generate a similar plot. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
