[jira] Updated: (HADOOP-4292) append() does not work for LocalFileSystem

     [ https://issues.apache.org/jira/browse/HADOOP-4292?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hairong Kuang updated HADOOP-4292:
----------------------------------

    Attachment: LFSAppend.patch

This patch marks "append" as "not supported" in ChecksumFileSystem. As a result, append is not supported in LocalFileSystem.

> append is supported by LocalFileSystem but it does not update crc when a file is appended. 
> When you enable checksum verification {{TestLocalFileSystem.testAppend}} fails. Since HADOOP-4277 is a blocker for 0.17  I am planning to disable this test in HADOOP-4277.
