Gopal V created HIVE-7313: ----------------------------- Summary: Allow session-level temp-tables to be marked as in-memory tables Key: HIVE-7313 URL: https://issues.apache.org/jira/browse/HIVE-7313 Project: Hive Issue Type: Improvement Components: Tez Reporter: Gopal V
When the hadoop-2.3C shims are in action, APIs which can pin small tables into memory are available. Any session with an in-memory table can create HDFS in-memory pools with default caching semantics and add its files into the cache pool. Example code to implement the behaviour was prototyped for the Tez Application Master, but the AM does not have enough information to determine the cache policies. https://github.com/rajeshbalamohan/hdfs-cache-tool/blob/master/src/main/java/org/apache/hadoop/hdfs/tools/HDFSCache.java#L74 -- This message was sent by Atlassian JIRA (v6.2#6252)
