Laurent Goujon updated HADOOP-10297: ------------------------------------ Attachment: hadoop-10297.patch Please review attached patch > FileChecksum should provide getChecksumOpt method > ------------------------------------------------- > > Key: HADOOP-10297 > URL: https://issues.apache.org/jira/browse/HADOOP-10297 > Project: Hadoop Common > Issue Type: Improvement > Reporter: Laurent Goujon > Attachments: hadoop-10297.patch > > > o.a.h.f.FileSystem has several methods which accepts directly or indirectly a > ChecksumOpt parameter to configure checksum options, but there's no generic > way of querying checksum options used for a given file. > MD5MD5CRC32FileChecksum used by DFSClient has a getChecksumOpt() but since > not just DistributedFileSystem is accepting a ChecksumOpt argument, but any > FileSystem subclass (although only DistributedFileSystem implements a > specific behaviour), I suggest to make getChecksumOpt an abstract method of > FileChecksum. This could be used by tools like DistCp to replicate checksum > options for example. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
