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] > NOTE: This is a branch-1 change only. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
