[jira] [Commented] (HBASE-14986) Display the key range for each region in the Regionserver UI
[ https://issues.apache.org/jira/browse/HBASE-14986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15061701#comment-15061701 ] Govind Kamat commented on HBASE-14986: -- This is not intended to be a panacea to assure users the key space is correctly split, but rather, would provide some additional information that alleviates the need to compute the ranges by hand if they want to view them. As Matteo mentioned above, for users who understand the splits they need implemented, this would give some quick verification that the regions are set up the way they would like them to be. > Display the key range for each region in the Regionserver UI > > > Key: HBASE-14986 > URL: https://issues.apache.org/jira/browse/HBASE-14986 > Project: HBase > Issue Type: New Feature > Components: regionserver, UI >Reporter: Govind Kamat >Assignee: Govind Kamat >Priority: Minor > Attachments: rs.jpg > > > The regionserver UI shows the start and end keys for each region, but it is > hard for users to deduce the byte range between these. > Unbalanced ranges can potentially lead to hot spots.

Also for users with variable length keys it will be a very misleading number. > Display the key range for each region in the Regionserver UI > > > Key: HBASE-14986 > URL: https://issues.apache.org/jira/browse/HBASE-14986 > Project: HBase > Issue Type: New Feature > Components: regionserver, UI >Reporter: Govind Kamat >Assignee: Govind Kamat >Priority: Minor > Attachments: rs.jpg > > > The regionserver UI shows the start and end keys for each region, but it is > hard for users to deduce the byte range between these. > Unbalanced ranges can potentially lead to hot spots.
