Subject [jira] [Commented] (HBASE-18843) Add DistCp support to incremental backup with bulk loading
Date Thu, 28 Sep 2017 03:38:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18843?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16183624#comment-16183624

Appy commented on HBASE-18843:
------------------------------

Thanks a lot [~elserj] for prompt back-and-forth! Yeah, let's revert it for now.

I looked around a bit more, and maybe have a more elegant solution.
Just override {{protected void doBuildListing(Path pathToListingFile, DistCpContext context)
throws IOException }} which is marked protected, so is meant to be.
For each path, do path=path.getParent() for 1 less time than is being done in current {{computeSourceRootPath}}.
Set the context appropriately so that the default implementation of {{computeSourceRootPath}}
does one more path.getParent. And that should be enough!

> Currently, we copy bulk loaded files to backup one-by-one on a client side (where backup
create runs). This has to be replaced with DistCp copying.
