> HadoopMapReduceEmbeddedSelfTest.testMultiReducerWholeMapReduceExecution fails
> with ~20% probability .
> Failure cause is either the 1st or 2nd marked line in the following code
> (org.apache.ignite.internal.processors.igfs.IgfsMetaManager#create) :
> {code}
> // Check: can we overwrite it?
> if (!overwrite)
> throw new
> IgfsPathAlreadyExistsException("Failed to create a file: " + path); // *****
> #1
> // Check if file already opened for write.
> if (oldInfo.lockId() != null)
> throw new IgfsException("File is already
> opened for write: " + path); // ***** #2
> {code}
> Diagnostic shows that the same file really attempted to be created several
> times on one thread.
