[jira] [Commented] (IGNITE-586) [Test] GridGgfsAbstractSelfTest.testFormat() fails on TC.

["Ivan Veselovsky (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14790906#comment-14790906 ] 

Ivan Veselovsky commented on IGNITE-586:
----------------------------------------

We revealed that the primary cause of the problem is that some tests bring IGFS into incorrect state: some entries in meta & data caches exist, but cannot be found by treversing the file system tree.
The fact is that at least renames cause such situation. The problem is localized tightly enough.
This happens at least in situation when a file cannot be moved to a destination folder where a file with the same short name already exists: in such situation the source file "disappears" from the file system, while still persists in meta cache.
