> If the editlog contains a transaction for creating an EC file, the NN will
> get blocked in {{waitForLoadingFSImage}} because the following call path:
> FSDirectory#addFileForEditLog --> FSDirectory#isInECZone -->
> FSDirectory#getECSchema --> ECZoneManager#getECSchema -->
> ECZoneManager#getECZoneInfo --> FSNamesystem#getSchema -->
> waitForLoadingFSImage
> This jira plans to fix this bug and also do some code cleanup.
