Re: [VOTE] Release Apache Hadoop 2.6.5 (RC1)

2016-10-05 Thread Akira Ajisaka


Hi Sangjin,

When using binary tarball, I'm seeing
"2016-09-27T18:26Z by sjlee from branch-2.6.5" in Web UI.
Can we rename it?

AFAIK, hadoop releases were built by hortonmu in 2014 and was renamed to 
jenkins.

Hi folks,

I have pushed a new release candidate (R1) for the Apache Hadoop 2.6.5
release (the next maintenance release in the 2.6.x release line). RC1
contains fixes to CHANGES.txt, and is otherwise identical to RC0.

Below are the details of this release candidate:

The RC is available for validation at:
http://home.apache.org/~sjlee/hadoop-2.6.5-RC1/.

The RC tag in git is release-2.6.5-RC1 and its git commit is
e8c9fe0b4c252caf2ebf1464220599650f119997.

The maven artifacts are staged via repository.apache.org at:
https://repository.apache.org/content/repositories/orgapachehadoop-1050/.

You can find my public key at
http://svn.apache.org/repos/asf/hadoop/common/dist/KEYS.

Please try the release and vote. The vote will run for the usual 5 days. I
would greatly appreciate your timely vote. Thanks!

Regards,
Sangjin

[jira] [Created] (HDFS-10968) BlockManager#isNewRack should consider decommissioning nodes

2016-10-05 Thread Jing Zhao (JIRA)

Jing Zhao created HDFS-10968:


 Summary: BlockManager#isNewRack should consider decommissioning 
nodes
 Key: HDFS-10968
 URL: https://issues.apache.org/jira/browse/HDFS-10968
 Project: Hadoop HDFS
  Issue Type: Sub-task
  Components: erasure-coding, namenode
Affects Versions: 3.0.0-alpha1
Reporter: Jing Zhao
Assignee: Jing Zhao


For an EC block, it is possible we have enough internal blocks but without 
enough racks. The current reconstruction code calls {{BlockManager#isNewRack}} 
to check if the target node can increase the total rack number for the case, 
which compares the target node's rack with source node racks:
{code}
for (DatanodeDescriptor src : srcs) {
  if (src.getNetworkLocation().equals(target.getNetworkLocation())) {
return false;
  }
}
{code}
However here the {{srcs}} may include a decommissioning node, in which case we 
should allow the target node to be in the same rack with it.

For e.g., suppose we have 11 nodes: h1 ~ h11, which are located in racks r1, 
r1, r2, r2, r3, r3, r4, r4, r5, r5, r6, respectively. In case that an EC block 
has 9 live internal blocks on (h1~h8 + h11), and one internal block on h9 which 
is to be decommissioned. The current code will not choose h10 for 
reconstruction because isNewRack thinks h10 is on the same rack with h9.

[jira] [Created] (HDFS-10967) Add configuration for BlockPlacementPolicy to deprioritize near-full DataNodes

2016-10-05 Thread Zhe Zhang (JIRA)

Zhe Zhang created HDFS-10967:


 Summary: Add configuration for BlockPlacementPolicy to 
deprioritize near-full DataNodes
 Key: HDFS-10967
 URL: https://issues.apache.org/jira/browse/HDFS-10967
 Project: Hadoop HDFS
  Issue Type: Improvement
  Components: namenode
Reporter: Zhe Zhang


Large production clusters are likely to have heterogeneous nodes in terms of 
storage capacity, memory, and CPU cores. It is not always possible to 
proportionally ingest data into DataNodes based on their remaining storage 
capacity. Therefore it's possible for a subset of DataNodes to be much closer 
to full capacity than the rest.

Notice that this heterogeneity is most likely rack-by-rack -- i.e. _m_ whole 
racks with low-storage nodes and _n_ whole racks with high-storage nodes. So 
It'd be very useful if we can deprioritize those near-full DataNodes as 
destinations for the 2nd and 3rd replicas.

[jira] [Created] (HDFS-10966) Enhance Dispatcher logic on deciding when to give up a source DataNode

2016-10-05 Thread Zhe Zhang (JIRA)

Zhe Zhang created HDFS-10966:


 Summary: Enhance Dispatcher logic on deciding when to give up a 
source DataNode
 Key: HDFS-10966
 URL: https://issues.apache.org/jira/browse/HDFS-10966
 Project: Hadoop HDFS
  Issue Type: Bug
  Components: balancer & mover
Reporter: Zhe Zhang
Assignee: Mark Wagner


When a {{Dispatcher}} thread works on a source DataNode, in each iteration it 
tries to execute a {{PendingMove}}. If no block is moved after 5 iterations, 
this source (over-utlized) DataNode is given up for this Balancer iteration (20 
mins). This is problematic if the source DataNode was heavily loaded in the 
beginning of the iteration. It will quickly encounter 5 unsuccessful moves and 
be abandoned.

We should enhance this logic by e.g. using elapsed time instead of number of 
iterations.
{code}
// Check if the previous move was successful
} else {
  // source node cannot find a pending block to move, iteration +1
  noPendingMoveIteration++;
  // in case no blocks can be moved for source node's task,
  // jump out of while-loop after 5 iterations.
  if (noPendingMoveIteration >= MAX_NO_PENDING_MOVE_ITERATIONS) {
LOG.info("Failed to find a pending move "  + noPendingMoveIteration
+ " times.  Skipping " + this);
resetScheduledSize();
  }
}
{code}

Xiaobing Zhou resolved HDFS-10950.

Resolution: Invalid

Essentially, test_resetacl calls setAcl, getacl_recursive calls get 
getAclStatus recursively, and setfacl_default calls setAcl again. They can be 
all covered by setAcl and getAclStatus. There' no point to verify them. 
Resolved this as invalid.
