Subject [jira] Updated: (HBASE-1970) Export does one version only; make it configurable how many it does
Date Fri, 13 Nov 2009 23:15:39 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1970?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack updated HBASE-1970:

    Attachment: exporter-v3.patch

This patch adds versions, starttime, and endtime optional arguments to the Exporter MR job.
 I tested it.  I got burned by the fact that versions default is 1 so couldn't figure why
only one version returned no matter how I set times but figured it in the end.  I improved
javadoc around the setTimeRange in Scan to note this.  I added tests to TestStoreScanner to
prove TimeRange works as expected too.

> I was playing with Export to backup all of a table.  A small change on the Scan saying
save all versions was all it took to back up all versions.  As is the Import did the right
thing.   Wouldn't take much to add versions and/or timerange as little config. on the Export
MR job.
