[jira] [Created] (HDDS-1220) KeyManager#openKey should release the bucket lock before doing an allocateBlock

Lokesh Jain created HDDS-1220:
---------------------------------

             Summary: KeyManager#openKey should release the bucket lock before doing an allocateBlock
                 Key: HDDS-1220
                 URL: https://issues.apache.org/jira/browse/HDDS-1220
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
            Reporter: Lokesh Jain
            Assignee: Lokesh Jain


Currently KeyManager#openKey makes an allocateBlock call without releasing the bucket lock. Since allocateBlock requires a rpc connection to SCM, the handler thread in OM would hold the bucket lock until rpc is complete. Since allocateBlock call does not require a bucket lock to be held, allocateBlock call can be made after releasing the bucket lock.
