Subject [jira] [Updated] (HADOOP-7178) FileSystem should have an option to control the .crc file creations at Local.
Date Sun, 03 Jul 2011 12:04:22 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-7178?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Uma Maheswara Rao G updated HADOOP-7178:
----------------------------------------

    Description: 
When we copy the files from DFS to local, it is creating the .crc files in local filesystem
for the verification of checksum. When user dont want to do any check sum verifications, this
files will not be useful. 

Command line already has an option ignoreCrc, to control this.
So, we should have the similar option on FileSystem also..... like fs.ignoreCrc().
 This should set the setVerifyChecksum to false and also should select the non CheckSumFileSystem
as local fs.

  was:
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.


        Summary: FileSystem should have an option to control the .crc file creations at Local.
 (was: copyToLocal API is creating .crc files in local, even after setting verifyChecksum
to false at client side.)
