HBase version is 0.98.1-cdh5.1.0. I copied phoenix-core-4.1.0.jar and phoenix-4.1.0-server-hadoop2.jar into /opt/cloudera/parcels/CDH-5.1.0-1.cdh5.1.0.p0.53/lib/hbase/lib/ folder, and restarted HBase. I can see the following output in RegionServer log. /opt/cloudera/parcels/CDH-5.1.0-1.cdh5.1.0.p0.53/lib/hbase/bin/../lib/phoenix-4.1.0-server-hadoop2.jar:/opt/cloudera/parcels/CDH-5.1.0-1.cdh5.1.0.p0.53/lib/hbase/bin/../lib/phoenix-core-4.1.0.jar
It seems like HBase has found the phoenix, and the SYSTEM.CATALOG table also is displayed on the HBase UI. But there are many similar errors as follows in RegionServer log. ERROR org.apache.hadoop.hbase.regionserver.RegionCoprocessorHost: Failed to load coprocessor org.apache.phoenix.coprocessor.GroupedAggregateRegionObserver java.io.IOException: No jar path specified for org.apache.phoenix.coprocessor.GroupedAggregateRegionObserver ERROR org.apache.hadoop.hbase.regionserver.RegionCoprocessorHost: Failed to load coprocessor org.apache.phoenix.coprocessor.MetaDataRegionObserver java.io.IOException: No jar path specified for org.apache.phoenix.coprocessor.MetaDataRegionObserver I don't know why these classes don't be found? When executing sqlline.py, got the following error, Error: ERROR 2006 (INT08): Incompatible jars detected between client and server. Ensure that phoenix.jar is put on the classpath of HBase in every region server: org.apache.hadoop.hbase.exceptions.UnknownProtocolException: No registered coprocessor service found for name MetaDataService in region SYSTEM.CATALOG,,1411367741031.d5be3a939a02d334dd3472016edbccc0. It seems like these errors were caused by the same reason.
