Till Westmann created ASTERIXDB-1405:
----------------------------------------
Summary: Sporadic compilation error
Key: ASTERIXDB-1405
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1405
Project: Apache AsterixDB
Issue Type: Bug
Components: AsterixDB, Optimizer
Reporter: Till Westmann
Assignee: Yingyi Bu
When running a simple query
{code}
drop dataverse test2 if exists;
create dataverse test2;
use dataverse test2;
create type anon as {
id: int
};
create dataset myset(anon) primary key id;
insert into dataset myset
for $i in range(1,1000000) return {"id": $i, "bla": $i};
count( for $i in dataset myset return $i );
{code}
I once saw this exception:
{code}
org.apache.hyracks.algebricks.common.exceptions.AlgebricksException: Could not
resolve type for function-call: asterix:dataset, Args:[AString: {myset}],please
check whether the used variables has been defined!

Other runs of the same query worked well. I did send some requests to the
Hyracks admin console while the request ran (not sure if there's a relationship
between these requests and the error.).
