[jira] [Updated] (HBASE-5509) MR based copier for copying HFiles (trunk version)
[ https://issues.apache.org/jira/browse/HBASE-5509?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Lars Hofhansl updated HBASE-5509: - Fix Version/s: (was: 0.94.1) (was: 0.96.0) I am not happy with this. I think other features (like hardlinks) are missing to make this scheme viable. Unscheduling. 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 is automatically generated by JIRA.

Another thought: It would be great if files outputted by SnapshotMR could be used with LoadIncrementalHFiles.

I made the following changes: 1. API changes for trunk. 2. Also copies and patches .tableinfo files as needed. 3. ImportTable can proceed even while HBase is down (HDFS needs to be up obviously). Regions will assigned upon HBase startup. 4. A ZK quorum can be optionally provided to assign imported regions right away (needed in trunk). 5. Some safety checks to verify the backup directory provided for import is in fact a backup directory (otherwise in some case adjacent directories were overwritten with temporary files).
