Example 1 with TableRegionModel

use of org.apache.hadoop.hbase.rest.model.TableRegionModel in project hbase by apache.

the class RegionsResource method get.

            model.add(new TableRegionModel(tableName.getNameAsString(), hri.getRegionId(), hri.getStartKey(), hri.getEndKey(), addr.getHostAndPort()));
