[DISCUSS] Removal of Llama support in next (2.8?) release of Impala
Impala's support for Llama, which adapts Yarn for low-latency query
engines, has long since bitrotted, and never worked very well. I propose
removing it from the next version of Impala - I don't know of any
deployments relying on its use.
The initial patch is here: http://gerrit.cloudera.org:8080/4445
If there's any discussion to be had, let's do it here.
Thanks!
Henry
