Subject [jira] Commented: (HADOOP-1084) updating a hdfs file, doesn't cause the distributed file cache to update itself
Date Fri, 29 Jun 2007 00:00:17 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12508965
] 

Owen O'Malley commented on HADOOP-1084:
---------------------------------------

With the block-level crc's coming, we should move to filestamps rather than checksums. It
is less precise, but the crc information is going away.

> If I delete and upload a new version of a file /user/owen/foo to HDFS and start my job
with hdfs://user/owen/foo as a cached file, it will use the previous contents.
