I do not think these are same issue, Please correct me if I am worng.
the SO link is abour SNN unable to establish communication with NN.
In my case I am unable to launch NN itself.
The NLP issue is at the highlighted line, but I am not sure how to go about
resolving it
/** Add a node child to the inodes at index pos.
* Its ancestors are stored at [0, pos-1].

child.spaceConsumedInTree(counts);
if (childDiskspace < 0) {

Re: unable to restart namenode on hadoop 1.0.4
Posted by Ravi Shetye <ra...@gmail.com>.
I do not think these are same issue, Please correct me if I am worng.
the SO link is abour SNN unable to establish communication with NN.
In my case I am unable to launch NN itself.
The NLP issue is at the highlighted line, but I am not sure how to go about
resolving it
/** Add a node child to the inodes at index pos.
* Its ancestors are stored at [0, pos-1].
* QuotaExceededException is thrown if it violates quota limit */
private <T extends INode> T addChild(INode[] pathComponents, int pos,
T child, long childDiskspace, boolean inheritPermission,
boolean checkQuota) throws QuotaExceededException {
INode.DirCounts counts = new INode.DirCounts();
child.spaceConsumedInTree(counts);
if (childDiskspace < 0) {
childDiskspace = counts.getDsCount();
}
updateCount(pathComponents, pos, counts.getNsCount(), childDiskspace,
checkQuota);
*T addedNode = ((INodeDirectory)pathComponents[pos-1]).addChild(*
* child, inheritPermission);*
if (addedNode == null) {
updateCount(pathComponents, pos, -counts.getNsCount(),
-childDiskspace, true);
}
return addedNode;
}
