bq. Will that make anything faster to have 1.2 as the default version instead of 1.0?
You can get to release notes from this thread: http://search-hadoop.com/m/pFao2kKHDm1 A few examples: MAPREDUCE-5368 <https://issues.apache.org/jira/browse/MAPREDUCE-5368>. Major improvement reported by zhaoyunjiong and fixed by zhaoyunjiong (mrv1) *Save memory by set capacity, load factor and concurrency level for ConcurrentHashMap in TaskInProgress* * * HADOOP-8971 <https://issues.apache.org/jira/browse/HADOOP-8971>. Major improvement reported by gopalv and fixed by gopalv (util) *Backport: hadoop.util.PureJavaCrc32 cache hit-ratio is low for static data (HADOOP-8926)** * On Thu, Oct 17, 2013 at 11:58 AM, Jean-Marc Spaggiari < [email protected]> wrote: > I think also we should be able to compile against v1 if required.
