Subject [jira] [Commented] (HBASE-15790) Force "hbase" ownership on bulkload
Date Fri, 06 May 2016 19:53:13 GMT

Jonathan Hsieh commented on HBASE-15790:
----------------------------------------

lgtm if the bot passes.

Seems like there could be rare race between 497/498 if there was a crash.  Probably not worth
fixing, but might be worth filing a follow up for hbck to check file owners/groups and perms
to find things that seem strange.  Wdyt?

{code}
 public Void run() throws Exception {
496	          FsPermission perms = FSUtils.getFilePermissions(fs, conf, HConstants.DATA_FILE_UMASK_KEY);
497	          fs.setOwner(dstPath, filesOwner, filesGroup);
498	          fs.setPermission(dstPath, perms);
499	          return null;
500	        }
{code}

> When a user different than "hbase" bulkload files, in general we end up with files owned
by a user different than hbase. sometimes this causes problems with hbase not be able to move
files around archiving/deleting.
> A simple solution is probably to change the ownership of the files to "hbase" during
bulkload.
