Date Mon, 23 Nov 2015 09:13:11 GMT
Nemon Lou created HIVE-12496:

             Summary: Open ServerTransport After MetaStore Initialization 
                 Key: HIVE-12496
             Project: Hive
          Issue Type: Improvement
          Components: Metastore
    Affects Versions: 1.2.1
         Environment: Standalone MetaStore, cluster mode(multiple instances)
            Reporter: Nemon Lou
            Assignee: Nemon Lou
            Priority: Minor

During HiveMetaStore starting,the following steps should be reordered:
1,Creation of TServerSocket
2,Creation of HMSHandler
3,Creation of TThreadPoolServer 

Step 2 involves some initialization work including :

TServerSocket shall be created after these initialization work  to prevent unnecessary waiting
from client side.And if there are errors during initialization (multiple metastores creating
default DB at the same time can cause errors),clients shall not connect to this metastore
as it will shuting down due to error.
