Bogdan Raducanu created HDFS-9516: ------------------------------------- Summary: truncate file fails with data dirs on multiple disks Key: HDFS-9516 URL: https://issues.apache.org/jira/browse/HDFS-9516 Project: Hadoop HDFS Issue Type: Bug Components: datanode Affects Versions: 2.7.1 Reporter: Bogdan Raducanu
FileSystem.truncate returns false (no exception) but the file is never closed and not writable after this. It seems to be because of copy on truncate which is used because the system is in upgrade state. In this case a rename between devices is attempted. See attached log and repro code. Probably also affects truncate snapshotted file when copy on truncate is also used. Possibly it affects not only truncate but any block recovery. I think the problem is in updateReplicaUnderRecovery {code} ReplicaBeingWritten newReplicaInfo = new ReplicaBeingWritten( newBlockId, recoveryId, rur.getVolume(), blockFile.getParentFile(), newlength); {code} blockFile is created with copyReplicaWithNewBlockIdAndGS which is allowed to choose any volume so rur.getVolume() is not where the block is located. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
