Updated the patch for branch-1 and master to ensure region name doesn't contain those long binary keys(Bytes.toString). However, start/end keys might contain(Bytes.toStringBinary). > list_regions may throw an error if a region is RIT > -------------------------------------------------- > > Key: HBASE-22735 > URL: https://issues.apache.org/jira/browse/HBASE-22735 > Project: HBase > Issue Type: Bug > Components: shell > Affects Versions: 1.5.0 > Reporter: Andrew Purtell > Assignee: Viraj Jasani > Priority: Minor > Fix For: 3.0.0, 1.5.0, 2.3.0, 2.2.1, 2.1.6, 1.3.6, 1.4.11 > > Attachments: HBASE-22735.branch-1.01.patch, > HBASE-22735.branch-1.02.patch, HBASE-22735.branch-1.03.patch, > HBASE-22735.master.01.patch, HBASE-22735.master.02.patch, > HBASE-22735.master.03.patch, Screen Shot 2019-07-30 at 11.53.53 PM.png, > screenshot.png > > > The 'list_regions' shell command gets a list of regions for a given table and > then prints them and some attributes such as the server where they are > located, current request count, data locality, and such. > However if a region is in transition the command might fail with > {{ERROR: undefined method `getDataLocality' for nil:NilClass}} > and there may be other ways this can happen.
