Hi, I have a hadoop cluster of 5 servers, version 0.21.0. On one of the servers i have a program which is writing to some file in HDFS, calling hflush and hsync after every write operation. When this server crashed (for example by power off) killing both DataNode and my little program, the data written to the file cannot be read for some time by another client. Duplication factor is set to 3. Situation changes after some time (several minutes), as i susspect NameNode needs time to proceed file recovering. When i try to append to this broken file, the AlreadyBeingCreatedException or RecoveryInProgressException exception occurring, but at the same time reading from the file gets no data (without any exeption).
Is this situation correct? Is there any way to check that this file is in the recovery state? If yes, program can wait some time for recovery finish. Thanks Darek C
