Arpit Agarwal commented on HDFS-4647:
-------------------------------------
Correct, this is during the rename step of the put.
The precondition failure is during the call to replaceRemovedChild4Reference
from createReferences4Rename.
{code}
private static void createReferences4Rename(final INode srcChild,
final byte[] srcChildName, final INodeDirectoryWithSnapshot srcParent,
final INodeDirectory dstParent) {
final INodeReference.WithCount ref;
if (srcChild.isReference()) {
ref = (INodeReference.WithCount)srcChild.asReference().getReferredINode();
} else {
ref = dstParent.asDirectory().replaceChild4Reference(srcChild);
}
srcParent.replaceRemovedChild4Reference(srcChild, ref, srcChildName);
}
{code}
