Subject [jira] [Commented] (HADOOP-7178) copyToLocal API is creating .crc files in local, even after setting verifyChecksum to false at client side.

    [ https://issues.apache.org/jira/browse/HADOOP-7178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13026080#comment-13026080

Todd Lipcon commented on HADOOP-7178:
-------------------------------------

I don't agree with the intent of this issue. Adding a new flag to turn on/off the *writing*
of checksums sounds reasonable -- but disabling the *writing* of checksums based on whether
you asked to verify it on the way out of HDFS seems like an unrelated choice.

> When we copy the files from DFS to local, it is creating the .crc file in local filesystem
for the verification of checksum even if we disable the checksum verification at client side.
>         When user does not want to do any checksum verification, then what will be the
use in creating of these files in local file system.
