[jira] [Created] (HDFS-8930) Block report lease may leak if the 2nd full block report comes when NN is still in safemode

Jing Zhao created HDFS-8930:
-------------------------------

             Summary: Block report lease may leak if the 2nd full block report comes when NN is still in safemode
                 Key: HDFS-8930
                 URL: https://issues.apache.org/jira/browse/HDFS-8930
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Jing Zhao
            Priority: Minor


This is a rare scenario in practice. If the NameNode is still in startup SafeMode while a DataNode sends it the 2nd FBR, the NameNode assigns the lease but rejects the report. The lease then leaves in NN until it expires.
