Andrey N. Gura commented on IGNITE-1666:
----------------------------------------
As I can see from code partition will be reserved only if scan query created
for scan of one particular partition. For common case with scan of all
partitions there si no logic for partitions reservation. So, despite we can't
reproduce the problem, it is still actual.
> Fallback for full scan query does not work

> Key: IGNITE-1666
> URL: https://issues.apache.org/jira/browse/IGNITE-1666
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: ignite-1.4
> Reporter: Andrey N. Gura
> Assignee: Diana Iakovleva
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h

> Fallback for full scan query doesn't work.
> Steps to reproduce (all in one thread):
> 1. Start N nodes, create cache and populate some entries to cache.
> 2. Stop some node.
> 3. Get iterator on the cache and fetch all entries one by one.
> 4. Repeat from step 2.
> On some iteration scan query fails with exception:
> {noformat}
> javax.cache.CacheException: class org.apache.ignite.IgniteCheckedException:
> Query execution failed: GridCacheQueryBean [qry=GridCacheQueryAdapter
> [type=SCAN, clsName=null, clause=null, filter=null, part=null, incMeta=false,

> In this case query should be retried (as well as for partition scan query).
