[jira] [Created] (HDFS-15735) NameNode memory Leak on frequent execution of fsck

Ravuri Sushma sree created HDFS-15735:
-----------------------------------------

             Summary: NameNode memory Leak on frequent execution of fsck  
                 Key: HDFS-15735
                 URL: https://issues.apache.org/jira/browse/HDFS-15735
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Ravuri Sushma sree
            Assignee: Ravuri Sushma sree


The memory of the cluster NameNode continues to grow, and the full gc eventually leads to the failure of the active and standby HDFS

Htrace is used to track the processing time of fsck

Checking the code it is found that the tracer object in NamenodeFsck.java was only created but not closed because of this the memory footprint continues to grow
