Kihwal Lee commented on HADOOP-8240: ------------------------------------ The new patch implements ChecksumOpt and updates API in both FileSystem and FileContext. This patch also includes: - related changes in HDFS. - a new common test for ChecksumOpt and another test that is DFS-specific. - an updated MR test case due to API change > Allow users to specify a checksum type on create() > -------------------------------------------------- > > Key: HADOOP-8240 > URL: https://issues.apache.org/jira/browse/HADOOP-8240 > Project: Hadoop Common > Issue Type: Improvement > Components: fs > Affects Versions: 0.23.0 > Reporter: Kihwal Lee > Assignee: Kihwal Lee > Fix For: 2.1.0-alpha > > Attachments: hadoop-8240.patch, hadoop-8240-trunk-branch2.patch.txt > > > Per discussion in HADOOP-8060, a way for users to specify a checksum type on > create() is needed. The way FileSystem cache works makes it impossible to use > dfs.checksum.type to achieve this. Also checksum-related API is at > Filesystem-level, so we prefer something at that level, not hdfs-specific > one. Current proposal is to use CreatFlag. -- This message is automatically generated by JIRA.
