[jira] [Created] (HDFS-16309) ViewFileSystem.setVerifyChecksum should not initialize all target filesystems

Abhishek Das created HDFS-16309:
-----------------------------------

             Summary: ViewFileSystem.setVerifyChecksum should not initialize all target filesystems
                 Key: HDFS-16309
                 URL: https://issues.apache.org/jira/browse/HDFS-16309
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Abhishek Das
            Assignee: Abhishek Das


Currently setVerifyChecksum and setWriteChecksum initializes all target file systems which causes delay in hadoop shell copy commands such as get, put, copyFromLocal etc.

This also eventually causes OOM.
