hellojinjie commented on HIVE-5820:
-----------------------------------
Same environment(CDH 4), same version of Hive, I also met the problem.
I use avro.schema.url to specify the url of the avsc
{code}
TBLPROPERTIES (
'avro.schema.url'='hdfs:///user/qos/workspaces/avro/Message.avsc')
{code}
During the query, the log also print the same error message.
But it does not affect the execution of Hive query.
