Alejandro Abdelnur commented on HADOOP-10750:
---------------------------------------------
A few minor things and we are ready to go:
*CachingKeyProvider.java*:
* Remove {{serialVersionUID}} from {{KeyNotFoundException}}
* no need for {{getCacheExtension()}}, {{getExtension()}} is generified
* the 2 {{rollNewVersion()}} methods must invalidate the metadatacache
*KMSConfiguration.java*:
. {{KEY_CACHE_TIMEOUT_DEFAULT}} should be higher, i.e. 10 mins
*KMSWebApp.java*:
. we should have a config property to disable cache, not wrapping the
keyprovider at all. default value, caching == TRUE
*KMS doc*:
. it should mention caching configs, timeouts and enable/disable
> KMSKeyProviderCache should be in hadoop-common
