Add Fail-Fast to Procedures by throwing exception out of Procedure constructor so if move but table is disabled or if master is going down, etc., we can give notice before the procedure is scheduled. Will help guard against scheduling Procedures that will have a hard time succeeding; e.g. a move when table is offline. Also fixed bug around table state where we presumed ENABLED though no entry in hbase:meta (we were using this mechanism for whether a table existed or not).

M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java Removed setting time setting table state; broke when using other than default environment edge masked by presumption that no state meant active. |
