Eric Payne commented on YARN-7411:
----------------------------------
[~sunilg] and [~leftnoteasy]. I backported this JIRA to branch-2 but had to
revert it when I discovered that it prevented nodemanagers from coming up if
there are extended resources defined.
Looking deeper, I discovered that this JIRA removed the following code in
{{ResourcePBImpl#initResources}}
{code}
-
- // Update missing resource information on respective index.
- updateResourceInformationMap(types);
- }
-
- private void updateResourceInformationMap(ResourceInformation[] types) {
- for (int i = 0; i < types.length; i++) {
- if (resources[i] == null) {
- resources[i] = ResourceInformation.newInstance(types[i]);
- }
- }
{code}
Further digging showed that this was put back in YARN-7483.
Next, I will attempt to backport these 2 patches together, but I thought it
would be better to revert YARN-7411 until I'm sure there are no more
dependencies.
