Upgraded APIs: Flink (0.8) and HBase (0.98.x) + profiles

I had to create an hadoop.core.version variable to manage the fact that cloudera has different versions for hadoop-core and hadoop-common..
Unfortunately I can't make it work..using avro for the serialization I get this error:

java.lang.RuntimeException: java.lang.NoSuchMethodException: org.apache.hadoop.hbase.Cell.<init>()
	at org.apache.avro.specific.SpecificData.newInstance(SpecificData.java:316)
	at org.apache.avro.specific.SpecificData.newRecord(SpecificData.java:332)

Do I have to configure something else?
