Eric Badger commented on YARN-9562:
-----------------------------------
{noformat:title=ImageTagToManifestPlugin.java}
Path manifestPath = new Path(manifestDir + hash);
FileSystem fs = manifestPath.getFileSystem(conf);
FSDataInputStream input;
try {
input = fs.open(manifestPath);
{noformat}
The code is failing on the fs.open(manifestPath), and manifestPath is getting
set to manifestDir + hash.
{noformat:title=ImageTagToManifestPlugin.java}
manifestDir = conf.get(NM_RUNC_IMAGE_TOPLEVEL_DIR) + "/manifests/";
{noformat}
manifestDir gets set by the code above. This implies that
{{NM_RUNC_IMAGE_TOPLEVEL_DIR}} is being set to /user/yarn/null somehow.
{noformat}
public static String NM_RUNC_IMAGE_TOPLEVEL_DIR =
IMAGE_TAG_TO_MANIFEST_PLUGIN_PREFIX + "image-toplevel-dir";
{noformat}
{{NM_RUNC_IMAGE_TOPLEVEL_DIR}} is set as such.
I'm not quite sure how it's possible that your config was set to /runc-root,
yet you got the /user/yarn/null path in your manifestPath. Are you sure that
the config was loaded correctly?

> This JIRA will be used to add the Java changes for the new
