Days before I have installed presto and ambari separately, officially ambari doesn’t support presto, you have to download ambari-presto-service and configure it yourself if you wanna manage presto on ambari.
version=`hdp-select status hadoop-client | sed 's/hadoop-client - ([0-9].[0-9]).*/1/'`
mkdir /var/lib/ambari-server/resources/stacks/HDP/$version/services/PRESTO
wget https://github.com/prestodb/ambari-presto-service/releases/download/v1.2/ambari-presto-1.2.tar.gz
tar -xvf ambari-presto-1.2.tar.gz -C /var/lib/ambari-server/resources/stacks/HDP/$version/services/PRESTO
mv /var/lib/ambari-server/resources/stacks/HDP/$version/services/PRESTO/ambari-presto-1.2/* /var/lib/ambari-server/resources/stacks/HDP/$version/services/PRESTO
rm -rf /var/lib/ambari-server/resources/stacks/HDP/$version/services/PRESTO/ambari-presto-1.2
chmod -R +x /var/lib/ambari-server/resources/stacks/HDP/$version/services/PRESTO/*
3.restart ambari-server
ambari-server restart
4.add presto service on ambari, please configure discovery.uri when you add presto service, e.g. discovery.uri: http://coordinator:8285
After doing this, you could add catalogs and use presto as query engine.
I did a simple query comparison between Tez and Presto, if you wanna accurate benchmark result, I think this benchmark test could help. The query is to calculate sum on a hive table.
Presto: 4s
presto:test> select sum(count) as sum from (
-> select count(*) as count from t0004998 where month = '6.5'
-> union
-> select count(*) as count from t0004998 where typestatus in ('VL2216','VL2217','VL2218','VL2219','VL2220')
-> union
-> select count(*) as count from t0004998 where countrycode in ('FAMILY','FORM','GENUS','KINGDOM','ORDER','PHYLUM','SPECIES')
-> ) t;

According to the result, MR is quicker than Tez on creation, but slower than Tez on query, along with query condition’s increase, MR’s query performance became worse.
But why MR is quicker than Tez on creation, currently I don’t know, need to be investigated later.
Maybe it has relationship with storage, I have checked the filesystem after the two kinds of creation, it’s different. MR has many small files, but Tez has one much bigger file.
I tested performance about MR and Tez on my laptop, it’s single server, so it’s not very accurate.
I create two tables to do the test which contains the datasets I downloaded from GBIF.

After I installed Tez, it’s ok to run hive jobs via Tez, but when I changed engine to MR, I got below error:

FAILED: Execution Error, return code -101 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask. DEFAULT_MR_AM_ADMIN_USER_ENV
I can’t see any useful information from logs, after long time’s investigating, I found hadoop-mapreduce-client-common-2.7.0.jar/hadoop-mapreduce-client-core-2.7.0.jar under Tez library were conflicting with hadoop version, my installed hadoop version was 2.8.2, so I removed the two jars.
After doing this, I could run hive on MR successfully..😀
From hive2 Hive-on-MR is not recommended, you could see the warning information when running hive cli
Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.
So I installed Tez to replace MR to run jobs, below are installation steps.
1.install Tez
1.1.down Tez and unpackage
wget http://ftp.jaist.ac.jp/pub/apache/tez/0.9.0/apache-tez-0.9.0-src.tar.gz
tar -zvxf apache-tez-0.9.0-src.tar.gz && cd apache-tez-0.9.0-src
1.2.compile and build Tez jar, you need install protobuf/maven before compiling
