Finally, the mystery has been solved.
Small remark before I explain everything.
The situation with only region is absolutely the same:
Fzzy: 1Q7iQ9JA
Next fzzy: F7dtxwqVQ_Pw -- the value I'm trying to find.
Fzzy: F7dt8QWPSIDw
Somehow FuzzyRowFilter has just omit my value here.
So, the

understand why with FuzzyFilter it goes from one region to another until it
stops at the value. I suppose if scanning process has started at once on
all regions
Scanning process does not start parallely
. But the normal scan from
client side will be sequential on the regions not parallel.

The situation with only region
Ted, thanks for the question.
There are results of investigation.
It seems I am mistaken. I thought that scanners are assigned to each
regions to scan (and do that in parallel) and that means each scanner
should start from the beginning of its region and then fall down to the
required record.
If its the same class and its not a patch, then the first class loaded wins.
So if you have a Class Foo and HBase has a Class Foo, your code will never see
the light of day.
Perhaps I'm stating the obvious but its something to think about when working w
Hadoop.

Ted,
that is correct.
HBase 0.92.x and we use part of the patch 6509.
I use the filter as a custom filter, it lives in separate jar file and goes
to HBase's classpath. I did not patch HBase.
Moreover I do not use protobuf's descriptions that comes with the filter in
patch. Only two classes I
In your original email you said the first key looked like start key of a
region, can you verify that ?
Thanks

To my knowledge CDH-4.1.2 is based on HBase 0.92.x
Looks like you were using patch from HBASE-6509 which was integrated to
trunk only.
Please confirm.
Copying Alex who wrote the patch.
Cheers
