[jira] [Commented] (HBASE-9389) Favorednodes command line not
verifying assignments correctly
[ https://issues.apache.org/jira/browse/HBASE-9389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13754533#comment-13754533 ]
Nicolas Liochon commented on HBASE-9389:
----------------------------------------
for verifyRegionPlacement:
bq. + * @param report
It should be @ return
But while this method now returns a report it's never used?
+ if (cfStatus.getPath().getName().startsWith(".") ||
+ HConstants.HBASE_NON_USER_TABLE_DIRS.contains(cfStatus.getPath().getName())) {
We were skipping the "technical directories", and .META., and now explicitly the system tables, but are we right to skip the system tables, .META. included? I could imagine that we want to use the favored node configuration for them as well.

> In manual testing, encountered an issue to do with the command line tool (HBASE-9116) not verifying the assignments correctly. Although the regions are assigned to the favored nodes, the verification/print showed otherwise.
> The command to reproduce the problem (after having created the tables, and loading some data):
> bin/hbase org.apache.hadoop.hbase.master.RegionPlacementMaintainer -tables cluster_test1,cluster_test2 -hbase_root /apps/hbase/data -v
