Doubt in File concat implementaion
Hi All,
Usually we can't ensure lastblock alwaysfull...please let me know purpose of following check..
long blockSize = trgInode.getPreferredBlockSize();
// check the end block to be full
final BlockInfo last = trgInode.getLastBlock();
if(blockSize != last.getNumBytes()) {
throw new HadoopIllegalArgumentException("The last block in " + target
+ " is not full; last block size = " + last.getNumBytes()
+ " but file block size = " + blockSize);
}
If it is issue, I'll file jira.
Following is the trace..
exception in thread "main" org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.HadoopIllegalArgumentException): The last block in /file_one.txt is not full; last block size = 14 but file block size = 134217728
