holes in tables.
Greetings all. How does one deals with holes in tables between
regions nowadays?
Name Region Server Start Key End Key

Note, I got "1cce.jpg 1udf.jpg" region followed by "3s3b.jpg 69yl.jpg";

Hi Jack,
Have a look into the JRuby source of that script. It is trivial to patch it so that it does what you want.

Re: holes in tables.

patch_meta.rb has some problems. I ran it, and it would create region
start/end combos, there were incorrect in terms of order, for example
"dab - cab", which is a region that is not right, because first key is
greater than end key. I guess what I really need is a very simple
tool, that takes something like this:
# add_empty_region.rb <table> <first key> <end key>
This way I can fill in the gap/whole, and be on my merry way. Right
now I resort to merging regions with hadoop fs -cp, which is a pain in
a butt if there are too many of them to merge.
Best,
-Jack

You could also have a go at https://issues.apache.org/jira/browse/HBASE-4009
Simple script based on the check_meta.rb to patch holes.

OfflineMetaRepair class is in 0.90.5
See HBASE-4377
But maybe you're looking for an online solution.
