---------------------------------------

             Summary: IGFS: File close should require only one meta transaction.
                 Key: IGNITE-2824
                 URL: https://issues.apache.org/jira/browse/IGNITE-2824
             Project: Ignite
          Issue Type: Bug
          Components: IGFS
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
             Fix For: 1.6


*Problem*
Have a look at {{IgfsOutputStreamImpl.onClose(boolean)}} method. It performs two sequential calls:
1) meta.unlock();
2) meta.updateParentListingAsync().

It spans two transactions and hence two 2PC routines, leading to less than optimal performance.

*Solution*
Update both file and it's parent in a single transaction.
