Ivan Veselovsky commented on IGNITE-1298:
-----------------------------------------
The solution plan looks like the following: make data and meta update
synchronous and pack them into one transaction.
Key methods are:
org.apache.ignite.internal.processors.igfs.IgfsDataManager.BlocksWriter#storeDataBlocks
org.apache.ignite.internal.processors.igfs.IgfsMetaManager#updateInfo
> Data and Meta in IGFS should be updated in one transaction.

> Key: IGNITE-1298
> URL: https://issues.apache.org/jira/browse/IGNITE-1298
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: ignite-1.4
> Reporter: Ivan Veselovsky
> Assignee: Ivan Veselovsky
> Fix For: ignite-1.4
>
>
> Tests written to check behavior IGNITE-1277 revealed problems on file data
> writing when some nodes have left the topology (see tests added in
> IGNITE-1277).
> In particular, meta data and file data are processed in separate
> transactions. So, one can complete while another may not. To fix that we need
> to link them together in one transaction.
> In more detail, this means that blocks writing and appropriate file size
> update should happen in one transaction.
