Hi folks, I was looking at the benchmark provided by Cloudera at http://blog.cloudera.com/blog/2014/05/new-sql-choices-in-the-apache-hadoop-ecosystem-why-impala-continues-to-lead/ . Is it real that Shark cannot execute some query if you don't have enough memory? And is it true/reliable that Impala overcome so much Spark when executing complex queries?
Best, Flavio
