Yongjun Zhang commented on HDFS-7312: ------------------------------------- Hi [~jprosser], Thanks for reporting the issue. FYI, HADOOP-11281.described the same issue. It's nice that you are working on. > Update DistCp v1 to optionally not use tmp location > --------------------------------------------------- > > Key: HDFS-7312 > URL: https://issues.apache.org/jira/browse/HDFS-7312 > Project: Hadoop HDFS > Issue Type: Improvement > Components: tools > Affects Versions: 2.5.1 > Reporter: Joseph Prosser > Assignee: Joseph Prosser > Priority: Minor > Original Estimate: 72h > Remaining Estimate: 72h > > DistCp v1 currently copies files to a tmp location and then renames that to > the specified destination. This can cause performance issues on filesystems > such as S3. A -skiptmp flag will be added to bypass this step and copy > directly to the destination. This feature mirrors a similar one added to > HBase ExportSnapshot > [HBASE-11119|https://issues.apache.org/jira/browse/HBASE-11119] -- This message was sent by Atlassian JIRA (v6.3.4#6332)
