HBA administrative tools do not work when specifying regionName
---------------------------------------------------------------
Key: HBASE-1175
URL: https://issues.apache.org/jira/browse/HBASE-1175
Project: Hadoop HBase
Issue Type: Bug
Components: client, master
Affects Versions: 0.19.0, 0.20.0
Reporter: Jonathan Gray
Assignee: Jonathan Gray
Fix For: 0.19.1, 0.20.0
HBaseAdmin administrative functions allow tableName or regionName through the
API. Things are okay if we pass tableName, but when using regionName the code
in HMaster is incorrect. It is expecting to be passed tableName and startRow,
but we are passing null and regionName. Patch will fix master to handle this
case properly.
Log for good measure:
