Lars Hofhansl resolved HBASE-5509. ---------------------------------- Resolution: Won't Fix Note needed, now that we have table snapshots. > MR based copier for copying HFiles (trunk version) > -------------------------------------------------- > > Key: HBASE-5509 > URL: https://issues.apache.org/jira/browse/HBASE-5509 > Project: HBase > Issue Type: Sub-task > Components: documentation, regionserver > Reporter: Karthik Ranganathan > Assignee: Lars Hofhansl > Attachments: 5509-v2.txt, 5509.txt > > > This copier is a modification of the distcp tool in HDFS. It does the > following: > 1. List out all the regions in the HBase cluster for the required table > 2. Write the above out to a file > 3. Each mapper > 3.1 lists all the HFiles for a given region by querying the regionserver > 3.2 copies all the HFiles > 3.3 outputs success if the copy succeeded, failure otherwise. Failed > regions are retried in another loop > 4. Mappers are placed on nodes which have maximum locality for a given region > to speed up copying -- This message was sent by Atlassian JIRA (v6.2#6252)
