Question

我正在尝试让Presto在Cloudera VM上运行（在使用普通的Hadoop和Amazon运行它之后）。基本上，我在同一节点上拥有一切（协调者，发现者，工作者）。我按照文档中的说明操作，并在运行选择查询时收到如下错误。我生成的UUID用于每个帖子的节点ID，但仍然是同一个问题。可以有人帮忙。

以下是Cloudera VM 4.3.0 VirtualBox映像上的配置：

等/ node.properties

node.environment=production
node.id=FA7BA366-0253-43CA-99DE-32DD4AC11C88
node.data-dir=/var/presto/data

等/ config.properties

coordinator=true
datasources=jmx,hive
http-server.http.port=8080
presto-metastore.db.type=h2
presto-metastore.db.filename=var/db/MetaStore
task.max-memory=1GB
discovery-server.enabled=true
discovery.uri=http://localhost:8080

等/目录/ hive.properties

connector.name=hive-cdh4
hive.metastore.uri=thrift://localhost:9083

等/目录/ jmx.properties

connector.name=jmx

等/ jvm.config

-server
-Xmx2G
-XX:+UseConcMarkSweepGC
-XX:+ExplicitGCInvokesConcurrent
-XX:+CMSClassUnloadingEnabled
-XX:+AggressiveOpts
-XX:+HeapDumpOnOutOfMemoryError
-XX:OnOutOfMemoryError=kill -9 %p
-XX:PermSize=150M
-XX:MaxPermSize=150M
-XX:ReservedCodeCacheSize=150M
-Xbootclasspath/p:/opt/presto/lib/floatingdecimal-0.1.jar

Cloudera VM附带jdk 6，Presto需要jdk 7，安装jdk7。不要使用rpm安装，它将删除jdk6，它可能会影响其他服务。我假设presto安装在/ opt / presto中，此目录（以及/ var / presto）由cloudera：cloudera拥有。启动Presto服务器：

PATH=/usr/java/jdk1.7.0_45/bin:$PATH /opt/presto/bin/launcher run

像客户端一样运行命令：

PATH=/usr/java/jdk1.7.0_45/bin:$PATH ./presto-cli-0.52-executable.jar --server localhost:8080 --catalog hive --schema default

没有可用于查询错误的节点
