Hi, guys
I applied the patches for HIVE-895 ( add SerDe for Avro serialized data
) and HIVE-3273 (Add avro jars into hive execution classpath ) on
Hive-0.9.0.
And then I ran the following command with hadoop-1.0.3 and avro-1.6.3
ant test -Dtestcase=TestCliDriver -Dqfile=avro_joins.q
-Dtest.silent=false
But I got an ERROR from hadoop in unit test. ( I can ran avro_joins.q
successfully in a real hadoop-1.0.3 cluster).
I found that IPC version 7 is from hadoop 2.x and version 4 is from
hadoop-1.x, but I didn't set hadoop 2.x in any properties files.
Do you know how this happened in unit test?
Thanks,
- Bing
