Jimmy Xiang updated HBASE-1936:
-------------------------------
Resolution: Fixed
Release Note:
With this patch, customer filters can be dropped into a pre-configured folder
(hbase.dynamic.jars.dir), which can be in hdfs. Region servers can pick them up
dynamically, no need to restart the cluster for the new filters to take effect.
However, if a filter class is already loaded, it won't be un-loaded. Therefore,
we can't load a new version of an existing class. Users have to have a proper
way to do filter class versioning.
Hadoop Flags: Reviewed
Status: Resolved (was: Patch Available)
Integrated into trunk and 0.95. Thanks Andy and Ted for the review.
> ClassLoader that loads from hdfs; useful adding filters to classpath without
> having to restart services
