Thrift JDBC Server描述
Thrift JDBC Server使用的是HIVE0.12的HiveServer2實現。能夠使用Spark或者hive0.12版本的beeline腳本與JDBC Server進行交互使用。Thrift JDBC Server默認監聽端口是10000。
使用Thrift JDBC Server前需要注意：
1、將hive-site.xml配置文件拷貝到$SPARK_HOME/conf目錄下；
2、需要在$SPARK_HOME/conf/spark-env.sh中的SPARK_CLASSPATH添加jdbc驅動的jar包
export SPARK_CLASSPATH=$SPARK_CLASSPATH:/home/Hadoop/software/mysql-connector-java-5.1.27-bin.jar
Thrift JDBC Server命令使用幫助：
cd $SPARK_HOME/sbin
start-thriftserver.sh --help
復制代碼
Usage: ./sbin/start-thriftserver [options] [thrift server options]
Spark assembly has been built with Hive, including Datanucleus jars on classpath
Options:
--master MASTER_URL spark://host:port, mesos://host:port, yarn, or local.
--deploy-mode DEPLOY_MODE Whether to launch the driver program locally ("client") or
on one of the worker machines inside the cluster ("cluster")
(Default: client).
--class CLASS_NAME Your application's main class (for Java / Scala apps).
--name NAME A name of your application.
--jars JARS Comma-separated list of local jars to include on the driver
and executor classpaths.
--py-files PY_FILES Comma-separated list of .zip, .egg, or .py files to place
on the PYTHONPATH for Python apps.
--files FILES Comma-separated list of files to be placed in the working
directory of each executor.
--conf PROP=VALUE Arbitrary Spark configuration property.
--properties-file FILE Path to a file from which to load extra properties. If not
specified, this will look for conf/spark-defaults.conf.
--driver-memory MEM Memory for driver (e.g. 1000M, 2G) (Default: 512M).
--driver-java-options Extra Java options to pass to the driver.
--driver-library-path Extra library path entries to pass to the driver.
--driver-class-path Extra class path entries to pass to the driver. Note that
jars added with --jars are automatically included in the
classpath.
--executor-memory MEM Memory per executor (e.g. 1000M, 2G) (Default: 1G).
--help, -h Show this help message and exit
--verbose, -v Print additional debug output
Spark standalone with cluster deploy mode only:
--driver-cores NUM Cores for driver (Default: 1).
--supervise If given, restarts the driver on failure.
Spark standalone and Mesos only:
--total-executor-cores NUM Total cores for all executors.
YARN-only:
--executor-cores NUM Number of cores per executor (Default: 1).
--queue QUEUE_NAME The YARN queue to submit to (Default: "default").
--num-executors NUM Number of executors to launch (Default: 2).
--archives ARCHIVES Comma separated list of archives to be extracted into the
working directory of each executor.
Thrift server options:
--hiveconf <property=value> Use value for given property
master的描述與Spark SQL CLI一致
beeline命令使用幫助：
cd $SPARK_HOME/bin
beeline --help
Usage: java org.apache.hive.cli.beeline.BeeLine
-u <database url> the JDBC URL to connect to
-n <username> the username to connect as
-p <password> the password to connect as
-d <driver class> the driver class to use
-e <query> query that should be executed
-f <file> script file that should be executed
--color=[true/false] control whether color is used for display
--showHeader=[true/false] show column names in query results
--headerInterval=ROWS; the interval between which heades are displayed
--fastConnect=[true/false] skip building table/column list for tab-completion
--autoCommit=[true/false] enable/disable automatic transaction commit
--verbose=[true/false] show verbose error messages and debug info
--showWarnings=[true/false] display connection warnings
--showNestedErrs=[true/false] display nested errors
--numberFormat=[pattern] format numbers using DecimalFormat pattern
--force=[true/false] continue running script even after errors
--maxWidth=MAXWIDTH the maximum width of the terminal
--maxColumnWidth=MAXCOLWIDTH the maximum width to use when displaying columns
--silent=[true/false] be more silent
--autosave=[true/false] automatically save preferences
--outputformat=[table/vertical/csv/tsv] format mode for result display
--isolation=LEVEL set the transaction isolation level
--help display this message
Thrift JDBC Server/beeline啟動
啟動Thrift JDBC Server：默認端口是10000
cd $SPARK_HOME/sbin
start-thriftserver.sh
如何修改Thrift JDBC Server的默認監聽端口號？借助於--hiveconf
start-thriftserver.sh --hiveconf hive.server2.thrift.port=14000
HiveServer2 Clients 詳情參見：https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients
啟動beeline
cd $SPARK_HOME/bin
beeline -u jdbc:hive2://hadoop000:10000/default -n hadoop
