Siddharth Seth and Gunther H. have run quite a few tests on a 20 node cluster running both basic mapreduce jobs like sort/wordcount as well as some hive queries. Are you asking if tez works on a larger cluster? There were a few bugs observed and fixed as a result. You may likely find more edge-case bugs but on the whole, the jobs ran successfully most of the time.
Tez code is compatible only with hadoop-2.1.0-beta/hadoop-trunk at the moment. There were numerous changes in yarn post 2.0.4/2.0.5 to stabilize the apis hence we made the call to aim for 2.1.0-beta compatibility. The aim is to stick to hadoop-2.1.0-beta after it is released. -- Hitesh On Jul 24, 2013, at 12:39 PM, Achal Soni wrote: > Has anybody tried and verified (and ideally benchmarked) Tez on an actual > cluster? > > We want to benchmark Pig on Tez on our test cluster to validate the > anticipated benefits. > > Related to this topic is the issue of Hadoop dependencies.
