[jira] [Created] (HDFS-10994) Support "XOR-2-1-64k" policy in "hdfs erasurecode" command

2016-10-10 Thread SammiChen (JIRA)

SammiChen created HDFS-10994:


 Summary: Support "XOR-2-1-64k" policy in "hdfs erasurecode" command
 Key: HDFS-10994
 URL: https://issues.apache.org/jira/browse/HDFS-10994
 Project: Hadoop HDFS
  Issue Type: Task
Reporter: SammiChen
Assignee: SammiChen


So far, "hdfs erasurecode" command supports three policies, RS-DEFAULT-3-2-64k, 
RS-DEFAULT-6-3-64k and RS-LEGACY-6-3-64k. This task is going to add XOR-2-1-64k 
policy to this command.

Thanks everyone for checking out this release! The vote passes with 15

I'll go ahead and wrap up the release, and will send an announcement in the
next day or two.

[jira] [Created] (HDFS-10993) rename may fail without a clear message indicating the failure reason.

2016-10-10 Thread Yongjun Zhang (JIRA)

Yongjun Zhang created HDFS-10993:


 Summary: rename may fail without a clear message indicating the 
failure reason.
 Key: HDFS-10993
 URL: https://issues.apache.org/jira/browse/HDFS-10993
 Project: Hadoop HDFS
  Issue Type: Bug
  Components: hdfs
Reporter: Yongjun Zhang


Currently the FSDirRenameOp$unprotectedRenameTo  looks like
{code}
 static INodesInPath unprotectedRenameTo(FSDirectory fsd,
  final INodesInPath srcIIP, final INodesInPath dstIIP, long timestamp)
  throws IOException {
assert fsd.hasWriteLock();
final INode srcInode = srcIIP.getLastINode();
try {
  validateRenameSource(fsd, srcIIP);
} catch (SnapshotException e) {
  throw e;
} catch (IOException ignored) {
  return null;
}

String src = srcIIP.getPath();
String dst = dstIIP.getPath();
// validate the destination
if (dst.equals(src)) {
  return dstIIP;
}

try {
  validateDestination(src, dst, srcInode);
} catch (IOException ignored) {
  return null;
}

if (dstIIP.getLastINode() != null) {
  NameNode.stateChangeLog.warn("DIR* FSDirectory.unprotectedRenameTo: " +
  "failed to rename " + src + " to " + dst + " because destination " +
  "exists");
  return null;
}
INode dstParent = dstIIP.getINode(-2);
if (dstParent == null) {
  NameNode.stateChangeLog.warn("DIR* FSDirectory.unprotectedRenameTo: " +
  "failed to rename " + src + " to " + dst + " because destination's " +
  "parent does not exist");
  return null;
}

fsd.ezManager.checkMoveValidity(srcIIP, dstIIP, src);
// Ensure dst has quota to accommodate rename
verifyFsLimitsForRename(fsd, srcIIP, dstIIP);
verifyQuotaForRename(fsd, srcIIP, dstIIP);

RenameOperation tx = new RenameOperation(fsd, srcIIP, dstIIP);

boolean added = false;

INodesInPath renamedIIP = null;
try {
  // remove src
  if (!tx.removeSrc4OldRename()) {
return null;
  }

  renamedIIP = tx.addSourceToDestination();
  added = (renamedIIP != null);
  if (added) {
if (NameNode.stateChangeLog.isDebugEnabled()) {
  NameNode.stateChangeLog.debug("DIR* FSDirectory" +
  ".unprotectedRenameTo: " + src + " is renamed to " + dst);
}

tx.updateMtimeAndLease(timestamp);
tx.updateQuotasInSourceTree(fsd.getBlockStoragePolicySuite());

return renamedIIP;
  }
} finally {
  if (!added) {
tx.restoreSource();
  }
}
NameNode.stateChangeLog.warn("DIR* FSDirectory.unprotectedRenameTo: " +
"failed to rename " + src + " to " + dst);
return null;
  }
{code}

There are several places that returns null without a clear message. Though that 
seems to be on purpose in the code, it left to user to guess what's going on.

It seems to make sense to have a warning for each failed scenario.

 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
