Hi,

I'm testing with Hive 0.9.0 (in Amazon EC2, but NOT emr).  I'm experiencing
a problem where DROP TABLE does not respect the IF EXISTS clause, so it
still throws an error when the table doesn't exist and this causes the
script to stop executing.  Here's what it looks like from the hive shell:

hive> DROP TABLE IF EXISTS recalc_aggregate_premium;

FAILED: Error in semantic analysis: Table not found recalc_aggregate_premium
Marc

Marc,
It seemed to work on my installation of Hive 0.9. Is this a table or a view
you are trying to drop?
Mind sharing the create table definition?

Hi Mark,

A table.  But it doesn't seem to matter.  I get this error on the DROP,
before even attempting to create a table.  I get the same thing for any
arbitrary table name.  For example:

hive> DROP TABLE IF EXISTS kdsjhfkjhds;
FAILED: Error in semantic analysis: Table not found kdsjhfkjhds
I think I found something, though.  This install is still using the Derby
metastore, and the hive web service is running, so I'm getting errors like
"A read-only user or a user in a read-only database…".  I'm guessing the
error above is just a consequence of this one-user limitation.  So, the
real issue is that the error message reported by "DROP TABLE IF EXISTS" is
mis-leading and obscures the real problem.
thanks,
Marc

Not sure how relevant it is but I faced a similar problem around ALTER
TABLE DROP PARTITION IF EXIST.

See https://issues.apache.org/jira/browse/HIVE-3576 for the specific
issue and my commands to reproduce it, and also try to perhaps set
hive.exec.drop.ignorenonexistent to true to see if it changes anything
for you?

Thanks, Harsh.   My issues seems to be related to the one-user limitation
of the derby metastore.  Once that issue was resolved the "table not found"
error went away.  It was just a misleading error message.

Thanks for the update, Marc. Could you please create a Hive JIRA for this?
Thanks!

Harsh, it's most likely the case with your JIRA as well that the error
message is misleading. Thanks for reporting it!
