["Andrew Wang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-11110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14139852#comment-14139852 ] 

Andrew Wang commented on HADOOP-11110:
--------------------------------------

[~tucu00] recommended:

bq. on flush() error (save) the JavaKeystoreProvider should drop the in-memory keystore (which has changes) and reload from file.

> Testing with the KMS backed by JKS reveals the following:
> {noformat}
> [root@dlo-4 ~]# hadoop key create testkey -provider kms://http@localhost:16000/kms
> testkey has not been created. Mkdirs failed to create file:xxxxx
> ....<stack trace>....
> [root@dlo-4 ~]# hadoop key list -provider kms://http@localhost:16000/kms
> Listing keys for KeyProvider: KMSClientProvider[http://localhost:16000/kms/v1/]
> testkey
> {noformat}
> The JKS still has the key in memory and serves it up, but will disappear if the KMS is restarted since it's not flushed to the file.
