@bartash I posted a patch on JIRA. Maybe someone can take a look at that. The gerrit process is a bit more than I bargained for. Thanks for the help.

> As I understand the code, Impala performs HMS/Kudu {{CREATE TABLE}} interaction as:
> * Create the table in Kudu
> * Register table with HMS
> * Drop the Kudu table on HMS error
> This is generally OK, except that it drops the table from Kudu on a {{TableAlreadyExists}} Exception.
> So, if I issue the same {{CREATE TABLE}} statement twice, the data will be dropped from Kudu on the second execution.
> This applies only to {{IF NOT EXISTS}} statements.
