> @tomscut Hi, does this WARN log be printed when only writing EC files ? This WARN logs also appeared in our cluster without writting any files, but not as many as you said. > I found that the block in the WARN log belongs to the file written a long time ago. So, I have some guesses: > > * is there a daemon thread calling this method? > * or other conditions trigger this method? > > Here is our 3-hour running log. >  Thanks @whbing for your comments. I found those logs were printed after completeFile. Triggered by FSDirWriteFileOp#completeFileInternal(). ``` private static boolean completeFileInternal( FSNamesystem fsn, INodesInPath iip, String holder, Block last, long fileId) throws IOException { (...) fsn.finalizeINodeFileUnderConstruction(src, pendingFile, Snapshot.CURRENT_STATE_ID, true); (...) return true; } ```  -- This is an automated message from the Apache Git Service.
