The Master is unable to continue startup because there is no Procedure to
assign
_hbase:meta_ (or _hbase:namespace_). To inject one, use the _HBCK2_ tool:
-``` HBASE_CLASSPATH_PREFIX=./hbase-hbck2-1.0.0-SNAPSHOT.jar hbase

+HBASE_CLASSPATH_PREFIX=./hbase-hbck2-1.0.0-SNAPSHOT.jar hbase

```
...where 1588230740 is the encoded name of the _hbase:meta_ Region.
