--------------------------------------
Summary: Document or fix new compat jar behavior.
Key: PHOENIX-5902
URL: https://issues.apache.org/jira/browse/PHOENIX-5902
Project: Phoenix
Issue Type: Bug
Affects Versions: 5.1.0, 4.16.0
Reporter: Lars Hofhansl
After PHOENIX-5808 (I think), the compat classes are no longer included into
Phoenix' server jar.
This causes the HBase regionservers to fail with:
2020-05-15 15:35:36,098 FATAL [RS_OPEN_PRIORITY_REGION-host:16201-1]
regionserver.HRegionServer: ABORTING region server think,16201,1589581955446:
The coprocessor org.apache.phoenix.coprocessor.UngroupedAggregateRegionObserver
threw java.lang.NoClassDefFoundError:
org/apache/phoenix/compat/hbase/CompatRpcControllerFactory
It is now necessary to copy lib/phoenix-hbase-compat-1.5.0-4.16.0-SNAPSHOT.jar
into HBase's lib directory as well.
The jar in the Phoenix directory is called:
phoenix-server-4.16.0-SNAPSHOT-hbase-1.5.jar, so I do not see why it could not
include the compatibility classes.
Alternatively we can rename that jar to just phoenix-server-4.16.0-SNAPSHOT.jar
and place the compatbility jar in Phoenix' top level directory and document the
change.
Marking as blocker for 4.16.0, because as is, it will bring HBase down hard
upon upgrade if this is not kept in mind.
