Eric Yang commented on HADOOP-16150: ------------------------------------ [~ste...@apache.org], in Hadoop wiki [create a github pull request|https://cwiki.apache.org/confluence/display/HADOOP/How+To+Contribute#HowToContribute-CreatingaGitHubpullrequest], it says that precommit job will search the URL that starts with "https://github.com" and ends with ".patch" in the JIRA issue. I set this jira to patch available and see if the patch gets tested. > checksumFS doesn't wrap concat(): concatenated files don't have checksums > ------------------------------------------------------------------------- > > Key: HADOOP-16150 > URL: https://issues.apache.org/jira/browse/HADOOP-16150 > Project: Hadoop Common > Issue Type: Bug > Components: fs > Affects Versions: 3.2.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Major > > Followon from HADOOP-16107. FilterFS passes through the concat operation, and > checksum FS doesn't override that call -so files created through concat *do > not have checksums*. > If people are using a checksummed fs directly with the expectations that they > will, that expectation is not being met. > What to do? > * fail always? > * fail if checksums are enabled? > * try and implement the concat operation from raw local up at the checksum > level > append() just gives up always; doing the same for concat would be the > simplest. Again, brings us back to "need a way to see if an FS supports a > feature before invocation", here checksum fs would reject append and concat -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
