Subject [jira] [Commented] (HIVE-17545) Make HoS RDD Cacheing Optimization Configurable
Date Mon, 25 Sep 2017 06:04:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16178573#comment-16178573
] 

Lefty Leverenz commented on HIVE-17545:
---------------------------------------

Spelling nit:  It should be "caching" instead of "cacheing" according to various dictionaries,
Wikipedia, and a reddit grammar discussion (https://www.reddit.com/r/grammar/comments/472c97/caching_or_cacheing_in_the_context_of_computers/).

> The RDD cacheing optimization add in HIVE-10550 is enabled by default. We should make
it configurable in case users want to disable it. We can leave it on by default to preserve
backwards compatibility.
