We have Hadoop cluster based on ambari Since thrift server have poor performance , we decided to replace it with presto Our current Hadoop cluster have the following machines 960 data node machines ( based on redhat 7 OS ) Few words about the presto- Presto (or PrestoDB) is an open source, distributed SQL query engine, designed from the ground up for fast analytic queries against data of any size. It supports both non-relational sources, such as the Hadoop Distributed File System (HDFS), We installed the new presto server as the following First we installed the OS ( redhat 7 ) , total 13 machines 1 machine for the presto coordinator And 12 machines for presto workers After installing the OS We installed successfully the presto ( presto coordinator + presto workers ) Now we are stuck about how to do the integration between presto cluster to the Hadoop cluster I will give short example about hive connector ( hive.properties ) we have the following variable hive.config.resources=/etc/hadoop/conf/core-site.xml,/etc/hadoop/conf/hdfs-site.xml since this file are located the data node machines and of course not on the presto worker machines , I assume that we need to copy these files from one of the data node machine to the presto workers machines am I right here ?
