Karthik Kambatla updated HADOOP-9064:
-------------------------------------
Attachment: hadoop-9064.patch
Uploading a path that does the following:
# Add findbugs exclusion for the reported warning: {{removeRenewAction}}
defines a generic type T that extends both {{FileSystem}} and {{Renewable}}.
findbugs was reporting warning about casting {{T}} to {{Renewable}}
# Merge tests for addRenewAction and removeRenewAction to remove redundancy,
and bump up the loop counter to accommodate any external delays. This increase
shouldn't affect the run time though.
> Augment DelegationTokenRenewer API to cancel the tokens on calls to
> removeRenewAction
