Description
org.apache.hadoop.hdfs.server.namenode.FSDirAppendOp.prepareFileForAppend(..)@189
file.recordModification(iip.getLatestSnapshotId()); file.toUnderConstruction(leaseHolder, clientMachine); fsn.getLeaseManager().addLease( file.getFileUnderConstructionFeature().getClientName(), file.getId()); LocatedBlock ret = null; if (!newBlock) { if (file.isStriped()) { throw new UnsupportedOperationException( "Append on EC file without new block is not supported."); }
In this code "UnsupportedOperationException" exception thows after marking file underConstruction. In this case file is opened without any "Open" editlogs, after some time lease manager close this file and add close edit log.
When SBN tail this edit log, it will fail with this exception.
