Let us say my log data that I want to place a log file into hive. And the log
file itself looks something like this:
Event_time, event_type, event_data_blob
And the blob data looks like
Key1=value1;key2=value2;key3=value3 ... keyn=valuen
This looks like maybe I start like this:

We've gotten this error a couple of times too - it is very misleading, not
correct at all. IIRC, I determined the root cause is selecting too many
input files (even though those do NOT get passed as arguments to transform
script). For example, this happened once we had a lot of dynamic
Usually this is caused by not having the mysql jdbc driver on the
classpath (it's not default included in hive).
Just put the mysql jdbc driver in the hive folder under lib/

Hi Bennie,
Thanks for the response !
I had CLASSPATH set to include
/usr/share/java/mysql.jar
... in addition, I just copied the mysql.jar to the lib directory of hive.

Any other ideas?
Thanks,

This definitely looks like a CLASSPATH error.
Where did you get the mysql.jar from ? Can you open it up and make sure that

with the RCfile format.
Is that
