 The DataNode reserves disk space for a full block when creating an RBW block 
 and will release the space when the block is finalized (introduced in 
 HDFS-6898) 
 But if the RBW file creation fails, the reserved space is not released back. 
 In a scenario, when the data node disk is full it causes no space left 
 {{IOException}}. Eventually even if the disk got cleaned,  the reserved space 
 is not release until the  Data Node is restarted

:) Reflection was working fine [~arpitagarwal] on 0th DN, but file creation was 
not failed may be because of multiple DNs in the MiniDFSCluster.
Anyway to avoid confusion, I have updated patch to start single DN and 
expecting exception during file creation. 

Seems some problem with jenkins due to maintenance shutdown. Will check the 
failures if any in the next build.

Right now I don't have unit test case to reproduce but tried stubbing

bq. In a scenario, when the data node disk is full it causes no space left 
IOException.
If this was truely the cause, it indicates {{getNextVolume()}} is not working 
properly. Normally {{DiskOutOfSpaceException}} is thrown before any space is 
reserved. So, if you believe it was caused by {{ENOSPACE}}, try finding out why 
the remaining space check was not working.  We have seen bad disks causing ext4 
to return incorrect values to the du command. In that case, the 
{{getAvailable()}} may not return correct result.

In any case, the proposed change is still good for any other types of file 
creation failures.  [~arpitagarwal], what do you think?

 The DataNode reserves disk space for a full block when creating an RBW block

 HDFS-6898) 
 But if the RBW file creation fails, the reserved space is not released back.

I am trying to find a way to mock BlockPoolSlice/java.io.File to reproduce it 
in junit test case. :( But couldn't do it successfully yet.
Down to File level can't be done as implementation looks different from java 7 
 8.

If its urgent for 2.7.1, we can go a head,, Otherwise I will try for some time 
to add test case.

Thanks [~kihwal], In that scenario we had only one disk path configured for 
data node.
Also for information, get availability on separate Java code  test  and df 
command gives available space from disk as 100+ GB but data node jmx report 
shown as 3 GB  after few hours  also.

In order to confirm the leak , I have ensured  through datanode heap dump 
analysis that reservedRBW variable in FSVolumeImpl is holding the number 
equalent to missing 100+ GB.

The patch looks good. Nitpick - you can simplify the try block.
{code}
try {
  return getBlockPoolSlice(bpid).createRbwFile(b);
} catch (IOException exception) {
{code}

+1 with that fixed.

Thanks for the review [~arpitagarwal], I am aware of HDFS-8072 which is 
handling when client terminate while DN receiving the block. 

However this issue happens during the construction of block receiver as per the 
stack I observed. (Right now I don't have stack.. will update description with 
exception stack trace some time tomorrow) 

I will wait for the jenkins result before updating the patch for the given 
review comment.
