Subject [jira] [Commented] (HDFS-12410) Ignore unknown StorageTypes
Date Mon, 11 Sep 2017 19:04:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16161798#comment-16161798
] 

Ajay Kumar commented on HDFS-12410:
-----------------------------------

[~chris.douglas] Instead of ignoring such storage types shall we assign them a default storage
type. 
In a scenario where end user mis-spelled storage type, first case(i.e ignoring them) will
result in disks being not used for storage. However if we assign all unknown storage type
to some default type and log an error message, end user can always go back and correct it.

> A storage configured with an unknown type will cause runtime exceptions. Instead, these
storages can be ignored/skipped.
