[GitHub] rdhabalia opened a new pull request #2636: Fix: NPE if messageId not present on create-sub admin-api call

rdhabalia opened a new pull request #2636: Fix: NPE if messageId not present on create-sub admin-api call
URL: https://github.com/apache/pulsar/pull/2636
 
 
   ### Motivation
   
   Right now, while creating subscription if user doesn't pass message-id then broker doesn't handle it properly which gives NPE and gives internal-server error to user.
   
   ```
   Message: null
   
   Stacktrace:
   
   java.lang.NullPointerException
           at org.apache.pulsar.broker.admin.PersistentTopics.createSubscription(PersistentTopics.java:885)
           at sun.reflect.GeneratedMethodAccessor199.invoke(Unknown Source)
   ```
   
   ### Modifications
   
   - take earliest-message id while creating subscription if user doesn't provide message-id.
