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.
> copyToLocal API is creating .crc files in local, even after setting
> verifyChecksum to false at client side.

> 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.
