------------------------------------
Summary: Race between partition eviction and re-creation
Key: IGNITE-6096
URL: https://issues.apache.org/jira/browse/IGNITE-6096
Project: Ignite
Issue Type: Bug
Affects Versions: 2.1
Reporter: Ilya Lantukh
Assignee: Ilya Lantukh
Fix For: 2.2
There are a number of cases that aren't handled correctly, leading to assertion
errors, grid hang-ups and data loss:
- PageMemoryImpl.refreshOutdatedPage(...) - if refreshed page is currently
scheduled for checkpoint, it will be stored if FileStore filled with zeroes.
Reading this page later will fail.
- GridCacheDatabaseSharedManager.restorePartitionState(...) -
grp.offheap().onPartitionInitialCounterUpdated(...) is called under meta page
write lock. If DataStore requires initialization, it will try to aquire write
lock for meta page again and hang up.
- GridDhtPartitionTopologyImpl.createPartition(...) and .localPartition0(...) -
if partition is present but has EVICTED state, we will try to create new
partition instance. However, DataStore for old partition might still be
present, and we will get AssertionError when we attempt to create new DataStore.
