Jing Zhao commented on HADOOP-10295: ------------------------------------ I will commit this patch later today if there is no more comment. > Allow distcp to automatically identify the checksum type of source files and > use it for the target > -------------------------------------------------------------------------------------------------- > > Key: HADOOP-10295 > URL: https://issues.apache.org/jira/browse/HADOOP-10295 > Project: Hadoop Common > Issue Type: Improvement > Components: tools/distcp > Affects Versions: 2.2.0 > Reporter: Jing Zhao > Assignee: Jing Zhao > Attachments: HADOOP-10295.000.patch, HADOOP-10295.002.patch, > hadoop-10295.patch > > > Currently while doing distcp, users can use "-Ddfs.checksum.type" to specify > the checksum type in the target FS. This works fine if all the source files > are using the same checksum type. If files in the source cluster have mixed > types of checksum, users have to either use "-skipcrccheck" or have checksum > mismatching exception. Thus we may need to consider adding a new option to > distcp so that it can automatically identify the original checksum type of > each source file and use the same checksum type in the target FS. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
