new 4ff4b99d3b4 HBASE-30192 ColumnFamilyDescriptor.getConfigurationValue
should also read the values map (#8295)
4ff4b99d3b4 is described below
commit 4ff4b99d3b4db409f415b5b4084461a2e4436bf6
Author: Junegunn Choi <[email protected]>
AuthorDate: Tue Jun 9 09:00:12 2026 +0900
HBASE-30192 ColumnFamilyDescriptor.getConfigurationValue should also read
the values map (#8295)
Since shell writes CF CONFIGURATION to values map (HBASE-20819),
getConfigurationValue should access it before checking
the legacy configuration map.
Note: changes behavior of a public method.
