-----------------------------------------
Summary: Improve documentation of hbase 1.x to 2.x potential
incompatibilities
Key: HBASE-26522
URL: https://issues.apache.org/jira/browse/HBASE-26522
Project: HBase
Issue Type: Improvement
Reporter: Bryan Beaudreault
We're working on a major upgrade of almost 900 tables across 100 production
clusters (and corresponding QA environment clusters). We've upgraded about 25%
of our QA environment and run into a series of incompatibilities along the way.
Most of them have been easy to get around, but I wanted to create this Jira to
collect them so that we can make an update to the docs for future upgraders.
My plan is to periodically edit this description to add to the list. If anyone
else has anything to contribute, feel free to edit as well or add a comment.
Incompatibilities to document:
- https://issues.apache.org/jira/browse/HBASE-15676 changed the serialized byte
string used for the fuzzy mask. FuzzyRowFilters created by older clients will
not match any rows in an hbase2 cluster.
