[jira] [Commented] (YARN-7875) AttributeStore for store and recover
attributes
[ https://issues.apache.org/jira/browse/YARN-7875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16421589#comment-16421589 ]
Sunil G commented on YARN-7875:
-------------------------------
Thanks [~bibinchundatt]. Few more minor nits.
# I think javadoc is missing in NodeAttributeStore for apis like *init* / *recover*
# {{enum StoreType}} has new entry named {{NODE_LABEL_ATTRIBUTE}} . This seems not correct. Its rather could be a simple NODE_ATTRIBUTE
# In {{getDefaultFSNodeAttributeRootDir}}, we use different patch for nodelabel and nodeattribute. Could u pls confirm that we are logging this name of dir in INFO log in *initStore*
# In below code, i think there is a chance of failure when custom class is configured by admin and if its not valid.

135 FileSystemNodeAttributeStore.class, NodeAttributeStore.class),
