[HBase-user] 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,

Simple script based on the check_meta.rb to patch holes.

But maybe you're looking for an online solution.

Greetings all.  How does one deals with holes in tables between
regions nowadays?

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

1. disable 'img644'
2.. running add_table.rb on 'img644'
