Bug in RAID FS (DistributedRaidFileSystem) unraid path ------------------------------------------------------
Key: MAPREDUCE-2570 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2570 Project: Hadoop Map/Reduce Issue Type: Bug Components: contrib/raid Reporter: Ramkumar Vadali Assignee: Ramkumar Vadali The "un-raid" path in DistributedRaidFileSystem goes through RaidNode.unRaidCorruptBlock(), which has a bug when the parity file is inside a HAR. The temporary file that contains the recovered block contents is created in the filesystem that hosts the parity file. In case the parity file is inside a HAR, its filesystem is HarFileSystem, which is read-only. In this case the temporary file creation will fail. The fix is a one-line change to use the underlying filesystem of the HAR. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
