Devaraj Das updated HBASE-9116:
-------------------------------
Attachment: 9116-5.txt
Sorry for the delay in responding. I couldn't get to it until now. Attached
patch takes care of the comments.
bq. Why updateFavoredNodes takes an OpenRegionRequest?
That's because the argument serves all the purpose of what is needed in the
updateFavoredNodes RPC. I am open to defining a new argument if you think
that'd be better.
bq. Is the hbase-site.xml change intentional?
Nope. Accidental..
bq. Can we create a similar putsToMetaTable method which takes a conf in
MetaEditor? We need to handle exceptions and close the table at the end.
Done (added close)
bq. Perhaps, it is better to log the stack trace as well
Done.
bq. Some function may not throw exception declared
Fixed.
bq. Good stuff. Is this still WIP? How can we use this? Edit the meta table
from hbase shell?
This is mostly complete. It needs more real life testing. The
RegionPlacementMaintainer in the patch has the commands to update meta (can be
run like a regular Java app). That's the tool added (which is the majority of
the code in this patch).
