1. 启动hive metastore
2. 启动hive thrift接口
参考:http://www.cnblogs.com/kisf/p/7497261.html
3. 下载presto server
wget https://repo1.maven.org/maven2/com/facebook/presto/presto-server/0.186/presto-server-0.186.tar.gz
4. 配置
config.properties
coordinator=true node-scheduler.include-coordinator=true http-server.http.port=20000 query.max-memory=40GB query.max-memory-per-node=4GB exchange.http-client.request-timeout=20s http-server.threads.max=400 discovery-server.enabled=true discovery.uri=http://10.183.225.158:20000
该配置将coordinate与worker配置再一台机器上。集群部署建议分开:
etc/config.properties包含 Presto Server 相关的配置,每一个 Presto Server 可以同时作为 coordinator 和 worker 使用。你可以将他们配置在一个节点上,但是,在一个大的集群上建议分开配置以提高性能。 coordinator 的最小配置: coordinator=true node-scheduler.include-coordinator=false http-server.http.port=9090 task.max-memory=1GB discovery-server.enabled=true discovery.uri= http://xx1:9090 worker 的最小配置: coordinator=false http-server.http.port=9090 task.max-memory=1GB discovery.uri= http://xx2:9090 可选的,作为测试,你可以在一个节点上同时配置两者: coordinator=true node-scheduler.include-coordinator=true http-server.http.port=9090 task.max-memory=1GB discovery-server.enabled=true discovery.uri=http://xx3:9090
node.properties

log.properties

etc/catalog/hive.properties
connector.name=hive-hadoop2 hive.metastore.uri=thrift://hadoop1:9083 hive.config.resources=/xxx/soft/hadoop-2.7.3/etc/hadoop/core-site.xml,/xxx/soft/hadoop-2.7.3/etc/hadoop/hdfs-site.xml hive.metastore.authentication.type=KERBEROS hive.metastore.service.principal=hive/hadoop1@JENKIN.COM hive.metastore.client.principal=presto@JENKIN.COM hive.metastore.client.keytab=/etc/presto/presto.keytab hive.hdfs.authentication.type=KERBEROS hive.hdfs.impersonation.enabled=false hive.hdfs.presto.principal=presto@JENKIN.COM hive.hdfs.presto.keytab=/etc/presto/presto.keytab
4. 启动presto coordinate
/usr/bin/nohup /xxx/soft/lesports-presto-server-0.176/bin/launcher run --node-config /etc/presto/01/node.properties --jvm-config /etc/presto/01/jvm.config --config /etc/presto/01/config.properties --log-levels-file /etc/presto/01/log.properties >/xxx/soft/lesports-presto-server-0.176/stdout.log 2>&1 &
这里为了做集群隔离把配置文件放到了另外的目录。
启动是否成功看日志,或者http://10.183.225.158:20000/看管理界面,或者:
netstat -nlp | grep 20000
5. 下载presto-cli
wget https://repo1.maven.org/maven2/com/facebook/presto/presto-cli/0.186/presto-cli-0.186-executable.jar
6. 改名为presto-cli
mv presto-cli-0.186-executable.jar presto-cli
7. 启动
./presto-cli --server hadoop1:20000 --catalog hive --schema jenkindb
10.183.225.158的hostname为hadoop1
8. 查询
presto:jenkindb> show tables; Table ---------- jenkintb test1 (2 rows) Query 20171020_023712_00002_a78ua, FINISHED, 1 node Splits: 18 total, 18 done (100.00%) 0:01 [2 rows, 49B] [2 rows/s, 51B/s] presto:jenkindb> select * from jenkintb; id | name ----+---------- 1 | jenkin 2 | jenkin.k 3 | anne (3 rows) Query 20171020_023724_00003_a78ua, FINISHED, 1 node Splits: 17 total, 17 done (100.00%) 0:00 [3 rows, 27B] [8 rows/s, 72B/s]
hive导入数据参考:http://www.cnblogs.com/kisf/p/7497261.html
问题解决:
问题:failed: No worker nodes available
解决:presto coordinate config.properties增加 node-scheduler.include-coordinator=true
问题:org.apache.hadoop.ipc.RemoteException: User: presto@JENKIN.COM is not allowed to impersonate root
解决:hive.properties增加 hive.hdfs.impersonation.enabled=false
