Bryan Beaudreault reassigned HBASE-26522:
-----------------------------------------
Assignee: Bryan Beaudreault
> 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
> Assignee: Bryan Beaudreault
> Priority: Minor
>
> 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.
