> We are experiencing a problem with the FuzzyRowFilter for HBase scan. We
> think that it is a bug.
> Fuzzy filter should pick a row if it matches filter criteria irrespective of
> other rows present in table but filter is dropping a row depending on some
> other row present in table.
> Details/Step to reproduce/Sample outputs below:
> Missing row key: \x9C\x00\x044\x00\x00\x00\x00
> Causing row key: \x9C\x00\x03\xE9e\xBB{X\x1Fwts\x1F\x15vRX
> Prerequisites
> 1. Create a test table. HBase shell command -- create 'fuzzytest','d'
> 2. Insert some test data. HBase shell commands:
> • put 'fuzzytest',"\x9C\x00\x044\x00\x00\x00\x00",'d:a','junk'
> • put 'fuzzytest',"\x9C\x00\x044\x01\x00\x00\x00",'d:a','junk'
> • put 'fuzzytest',"\x9C\x00\x044\x00\x01\x00\x00",'d:a','junk'
> • put 'fuzzytest',"\x9C\x00\x044\x00\x00\x01\x00",'d:a','junk'
> • put 'fuzzytest',"\x9C\x00\x044\x00\x01\x00\x01",'d:a','junk'
> • put 'fuzzytest',"\x9B\x00\x044e\xBB\xB2\xBB",'d:a','junk'
> • put 'fuzzytest',"\x9D\x00\x044e\xBB\xB2\xBB",'d:a','junk'
> Now when you run the code, you will find \x9C\x00\x044\x00\x00\x00\x00 in
> output because it matches filter criteria. (Refer how to run code below)
> Insert the row key causing bug:
> HBase shell command: put
> 'fuzzytest',"\x9C\x00\x03\xE9e\xBB{X\x1Fwts\x1F\x15vRX",'d:a','junk'
> Now when you run the code, you will not find \x9C\x00\x044\x00\x00\x00\x00 in
> output even though it still matches filter criteria.
