Date Wed, 02 Apr 2014 15:55:16 GMT
Sean Busbey created ACCUMULO-2613:
-------------------------------------

             Summary: Take advantage of HDFS caching
                 Key: ACCUMULO-2613
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2613
             Project: Accumulo
          Issue Type: Improvement
            Reporter: Sean Busbey
            Priority: Critical
             Fix For: 1.7.0


Hadoop 2.3.0 added [HDFS caching|http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/CentralizedCacheManagement.html].

We should use this for small internal use tables (like !METADATA) and we should probably have
a configurable option to use it for tables, with a stern warning that it should only be enabled
on small tables that will be frequently used.
