Subject Hive: Centralized HDFS Caching
Date Fri, 01 Aug 2014 10:43:10 GMT
Hi.

in Hive can I make use of the centralized cache management introduced in Hadoop
2.3
(http://hadoop.apache.org/docs/r2.3.0/hadoop-project-dist/hadoop-hdfs/CentralizedCacheManagement.html)?
If not implemented yet, is this on the roadmap?

My use case is that I want to pin a fact table that needs to be queried
frequently into memory.

Impala already supports this as per the Cloudera documentation
http://www.cloudera.com/content/cloudera-content/cloudera-docs/Impala/latest/Installing-and-Using-Impala/ciiu_perf_hdfs_caching.html

Thanks
uli
