Gopal V commented on HIVE-18665: -------------------------------- Not sure if that ever gets triggered, but it is pretty much a toss-up on whether to force affinity or not. > LLAP: Ignore cache-affinity if the LLAP IO elevator is disabled > --------------------------------------------------------------- > > Key: HIVE-18665 > URL: https://issues.apache.org/jira/browse/HIVE-18665 > Project: Hive > Issue Type: Bug > Components: llap > Affects Versions: 3.0.0 > Reporter: Gopal V > Assignee: Gopal V > Priority: Major > Attachments: HIVE-18665.1.patch > > > SplitLocationProvider removes HDFS locality in LLAP, causing more network > traffic when reading file formats which aren't currently cached. > In the absence of the IO elevator, cache affinity should be disabled. > This information is encoded into the MapWork in deriveLlapIoDescString, move > this to an Enum type for comparisons. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
