Datastax 6 独立分析服务器

Question

我下载了 datastax 6 并希望启动一个（在 mac El Capitan 上）分析（spark 很好，但 spark + search 会很好）。我提取了gz，配置了目录结构并执行了dse cassandra -ks。启动似乎工作得很好，我可以进入火花主节点，问题是当我运行dse spark-sql（或只是火花）时。我经常收到以下错误： 是否可以设置单个节点进行开发？

Answer 1

检查dse.yaml 中的/var/lib/... 中的目录 - 您应该对它们具有写访问权限...例如，检查 DSEFS 目录是否配置正确、AlwaysOn SQL 目录等。

但实际上，问题应该通过将 DSE 启动为 dse cassandra -s -k 而不是 -sk...

附：我正在使用以下脚本将日志等指向特定目录：

export CASSANDRA_HOME=WHERE_YOU_EXTRACTED
export DATA_BASE_DIR=SOME_DIRECTORY
export DSE_DATA=${DATA_BASE_DIR}/data
export DSE_LOGS=${DATA_BASE_DIR}/logs
# set up where you want log so you don’t have to mess with logback.xml files
export CASSANDRA_LOG_DIR=$DSE_LOGS/cassandra
mkdir -p $CASSANDRA_LOG_DIR
# so we don’t have to play with dse-spark-env.sh
export SPARK_WORKER_DIR=$DSE_DATA/spark/worker
# new setting in 6.0, in older versions set SPARK_LOCAL_DIRS
export SPARK_EXECUTOR_DIRS=$DSE_DATA/spark/rdd
export SPARK_LOCAL_DIRS=$DSE_DATA/spark/rdd
mkdir -p $SPARK_LOCAL_DIRS
export SPARK_WORKER_LOG_DIR=$DSE_DATA/spark/worker/
export SPARK_MASTER_LOG_DIR=$DSE_DATA/spark/master
# if you want to run the always on sql server
export ALWAYSON_SQL_LOG_DIR=$DSE_DATA/spark/alwayson_sql_server
export ALWAYSON_SQL_SERVER_AUDIT_LOG_DIR=$DSE_DATA/spark/alwayson_sql_server
# so tomcat logs for solr goes to a place we know
export TOMCAT_LOGS=$DSE_LOGS/tomcat

PATH=${CASSANDRA_HOME}/bin:${CASSANDRA_HOME}/resources/cassandra/tools/bin:$PATH
