guluo updated HBASE-28778:
--------------------------
Description:
The reason:
For table.jsp, NPE may occur when calling master.getConnection() while Master
is initializing.
asyncClusterConnection will only be initialized when HMaster call method
setupClusterConnection,
so before that, asyncClusterConnection is null, at this moment, we would get
NPE if opening table.jsp.
procedure.jsp and master-status may also encounter NPE for the similar reason.
Error Message：
java.lang.NullPointerException: Cannot invoke
"org.apache.hadoop.hbase.procedure2.ProcedureExecutor.getProcedures()" because
"procExecutor" is null at
