[jira] Created: (HBASE-1330) binary keys broken on trunk
binary keys broken on trunk
---------------------------
Key: HBASE-1330
URL: https://issues.apache.org/jira/browse/HBASE-1330
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.0
Reporter: ryan rawson
Fix For: 0.20.0
Attachments: HBASE-1330.patch
The symptom is commits fail with 'table not found' exception - even though the table does in fact exist!
Digging in a little with debug logs indicate that getClosestRowBefore() is returning NULL, which for a table that exists should never be! A key always falls into a region - either the first or the last one at the very least.

[jira] Updated: (HBASE-1330) binary keys broken on trunk

this is a typical META bug - using the normal Bytes comparator to compare the 'row' section causes problems when the first byte is '\0'. So if you have keys that start with a value < ',', most common in the binary key case (when the first byte is '\0'), you end up with incorrect storing saying things like:
table,,1234 > table,\0,1234
which is not correct. since [] < '\0'.

turns out the clone of a comparator loses the 'meta-ness' or 'root-ness'.
