Yet another approach is to transform your keys into byte comparable values that preserve your desired sort order, and store that instead. The ICU library has the ability to do this for various collations of UTF strings: http://userguide.icu-project.org/collation/architecture#TOC-Sort-Keys So for

Tom, another approach you could take would be to store an ASCII encoded version of the string as the row key or column qualifier, and then the full UTF-8 string elsewhere (e.g. in the cell value, or even later in the row key). That wouldn't work out the fine sorting (whether "è" sorts before or

Storing the bytes as native UTF-16 or UTF-32 will not help. Even strings in UTF-8 format can be sorted by their code points when stored as bytes. Unfortunately, that's not really useful for collation as characters like "è" (U+00E8) should appear between "e" (U+0065) and "f" (U+0066), but the code

Is there any way to control introduce a different ordering scheme from the base comparable bytes? My use case is that I am using UTF-8 data for my keys, and I would like to have scans use UTF-8 collation. Could this be done by providing an alternate implementation of WritableComparable? Thanks i

Hi, We had the same problem. We solve it this way: hbase zk_cli -ls /hbase/tables The table was still on Zookeeper. Deleted the table from zookeeper (rmr). Restart Hbase Masters, restart hbase region servers. Miguel Costa On 05/07/2012 06:42 PM, Ey-Chih chow wrote: If we use the class Cl
