Could you please post your SQL DDL statement? How many URLs do you have in your
external table? Also, your HASH dist table - how many buckets are defined, if
any? Are the # of URLs more than the # of buckets or
default_hash_table_bucket_number value? Perhaps you can attach your
hawq-site.xml file as well.

Hi,all:
I am testing hawq 2.0.0 , and I find a problem like this:
I load data from an external table (created using "like target_table"
statement) ,
if the target table was distributed by some column(s), it raise this error:
External scan error: There are more external files (URLs) than primary
segments that can read them (COptTasks.cpp:1756)
if the target table was distributed randomly, it works well,
I don't set any parameter special,does anybody know how to resolve this problem?
thanks a lot.
