SQL status code to indicate success or failure of query

[Du Li]

Hi,

After executing sql() in SQLContext or HiveContext, is there a way to tell 
whether the query/command succeeded or failed? Method sql() returns SchemaRDD 
which either is empty or contains some Rows of results. However, some queries 
and commands do not return results by nature; being empty is not indicative of 
their status of execution. For example, if the command is to create/drop a 
table, how could I know if the table has really been created/dropped? If it 
fails, is there a status code or something I could check to tell the reasons 
for failure?

Thanks,
Du
