Steve Loughran commented on HDFS-8705:
--------------------------------------
I should add that the locale most likely to break is turkey, where
{{"I".toLowerCase()!="i"}}, so matches the policy {{"lazy_persist"}} wont match
{{"LAZY_PERSIST"}}
> BlockStoragePolicySuite uses equalsIgnoreCase for name lookup, won't work in
> all locales

> Key: HDFS-8705
> URL: https://issues.apache.org/jira/browse/HDFS-8705
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Priority: Minor
>
> Looking at {{BlockStoragePolicySuite.getPolicy(name)}}, is using
> {{equalsIgnoreCase()}} to find a policy which matches a name.
> This will not work in all locales. It must use
> {{toLowerCase(Locale.ENGLISH).equals(name)}}
