ClosedChannelException when read dataset #805

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
=======================================
I am counting records (300G) and am getting an exception:
Unsupported type: RECORD [AsterixException]

It doesn't reproduce at small scale (on the same cluster, same data).

Query:
=======
use dataverse kereno;

for $t in dataset page_views
return {
  "count": count($t)
};

Stack:

That's not a valid query, but we probably can report the error message at 
compile time. 
Count is an aggregation function, but $t's type is record instead of a 
collection.

I guess this is what you want:
count(for $t in dataset page_views return $t);

I removed the group-by and its rebinding to a list, hence as you said the right 
way is as follows:

use dataverse kereno;
count(for $t in dataset page_views return $t);

which returns a null[], see stack below:

It looks like the file I/O has some issue.
Do you have disk failures on that machine?

Or the file is closed or has not been opened before being read? If so, it 
should be a bug.
It seems LSM related.  I assign this issue to Young-Seok.

No disk failures. 
I will see with Young-Seok, thanks.

Keren, for the issue below (from your comment 3), I believe it is/can be 
related to 
Issue 16: count( dataset('dataset-name') ); should return count

use dataverse kereno;
count(for $t in dataset page_views return $t);

which returns a null[], see stack below:

Kharruam, they are separate issues.  This one is a runtime issue - buffer cache 
has closed channel.  The old one was a compiler issue.

The exception stack seems that some concurrent operations(at least one writer) 
were going on. 
Is this reproducible?
