spark tachyon 搭建 配置

spark1.5.1 支持 tachyon0.7.1

jdk需要1.7

1.spark

下载spark source

http://spark.apache.org/downloads.html

编译spark

export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m"

mvn -Dhadoop.version=2.3.0 -DskipTests clean package

spark-env.sh

因为需要访问hdfs，hive，所以需要压缩lzo，和mysql

export SPARK_CLASSPATH=$SPARK_CLASSPATH:/data/hadoop/hadoop-2.3.0-cdh5.1.0/share/hadoop/common/hadoop-lzo-0.4.20-SNAPSHOT.jar
export SPARK_LIBRARY_PATH=$SPARK_LIBRARY_PATH:/data/hadoop/hadoop-2.3.0-cdh5.1.0/share/hadoop/common/hadoop-lzo-0.4.20-SNAPSHOT.jar
export SPARK_CLASSPATH=$SPARK_CLASSPATH:/data/hadoop/spark/spark-1.5.1-bin-hadoop2.3/lib/mysql-connector-java-5.1.20-bin.jar

export SPARK_PID_DIR=/data/hadoop/spark/spark-1.5.1-bin-hadoop2.3

写slave文件

host136
host137
host138

添加配置文件到conf里：

core-site.xml

hdfs-site.xml

hive-site.xml

修改hive-site.xml

<property>
  <name>hive.metastore.warehouse.dir</name>
  <value>tachyon://host136:19998/warehouse</value>
</property>

2.tachyon

下载tachyon，http://www.tachyon-project.org/

编译tachyon

mvn clean package -Djava.version=1.7 -Dhadoop.version=2.3.0 -DskipTests

修改配置：tachyon-env.sh

export TACHYON_RAM_FOLDER=/data/hadoop/spark/tachyon-0.7.1-2.3/data
//内存数据mount目录
fi

if [ -z "$JAVA_HOME" ]; then
  export JAVA_HOME="$(dirname $(which java))/.."
fi

export JAVA="${JAVA_HOME}/bin/java"
export TACHYON_MASTER_ADDRESS=host136

#hdfs
export TACHYON_UNDERFS_ADDRESS=hdfs://mycluster
#-Dtachyon.master.journal.folder=hdfs://mycluster/tachyon/journal/
#export TACHYON_UNDERFS_ADDRESS=${TACHYON_UNDERFS_ADDRESS:-hdfs://localhost:9000}
#使用内存大小
export TACHYON_WORKER_MEMORY_SIZE=20GB
export TACHYON_UNDERFS_HDFS_IMPL=org.apache.hadoop.hdfs.DistributedFileSystem
export TACHYON_WORKER_MAX_WORKER_THREADS=2048
export TACHYON_MASTER_MAX_WORKER_THREADS=2048

export TACHYON_SSH_FOREGROUND="yes"
export TACHYON_WORKER_SLEEP="0.02"

 可以配置多level数据

export TACHYON_JAVA_OPTS+="
  -Dlog4j.configuration=file:$CONF_DIR/log4j.properties
  -Dtachyon.debug=false
  -Dtachyon.worker.tieredstore.level.max=1
  -Dtachyon.worker.tieredstore.level0.alias=MEM
  -Dtachyon.worker.tieredstore.level0.dirs.path=$TACHYON_RAM_FOLDER
  -Dtachyon.worker.tieredstore.level0.dirs.quota=$TACHYON_WORKER_MEMORY_SIZE
  -Dtachyon.underfs.address=$TACHYON_UNDERFS_ADDRESS
  -Dtachyon.underfs.hdfs.impl=$TACHYON_UNDERFS_HDFS_IMPL
  -Dtachyon.data.folder=$TACHYON_UNDERFS_ADDRESS/tmp/tachyon/data
  -Dtachyon.worker.max.worker.threads=$TACHYON_WORKER_MAX_WORKER_THREADS
  -Dtachyon.workers.folder=$TACHYON_UNDERFS_ADDRESS/tmp/tachyon/workers
  -Dtachyon.worker.memory.size=$TACHYON_WORKER_MEMORY_SIZE
  -Dtachyon.worker.data.folder=/tachyonworker/
  -Dtachyon.master.max.worker.threads=$TACHYON_MASTER_MAX_WORKER_THREADS
  -Dtachyon.master.worker.timeout.ms=60000
  -Dtachyon.master.hostname=$TACHYON_MASTER_ADDRESS
  -Dtachyon.master.journal.folder=$TACHYON_HOME/journal/
  -Dorg.apache.jasper.compiler.disablejsr199=true
  -Djava.net.preferIPv4Stack=true
"

写slaves,workers

host136
host137
host138

添加配置文件到conf：

hdfs-site.xml

core-site.xml

在core-site.xml中添加

<property>
  <name>fs.tachyon.impl</name>
    <value>tachyon.hadoop.TFS</value>
    </property>
    <property>
      <name>fs.tachyon-ft.impl</name>
        <value>tachyon.hadoop.TFSFT</value>
     </property>

3启动服务：

tachyon：

需要用户有sudo权限，或是用root执行tachyon的mount操作

如果不想每次启动Tachyon都挂载一次RamFS，可以先使用命令 bin/tachyon-mount.sh Mount workers 或 bin/tachyon-mount.sh SudoMount workers 挂载好所有RamFS，然后使用 bin/tachyon-start.sh all NoMount 命令启动Tachyon。
		
		bin/tachyon format
		bin/tachyon-mount.sh SudoMount workers
		bin/tachyon-start.sh all NoMount
		bin/tachyon-stop.sh

当添加一个tachyon节点

bin/tachyon formatWorker
bin/tachyon-mount.sh  SudoMount local
bin/tachyon-start.sh  worker NoMount

 spark：

bin/spark-sql --master spark://host136:7077
bin/spark-shell --master spark://host136:7077

 4.spark操作tachyon

用spark直接通过tachyon读取hdfs数据：

var textFile = sc.textFile("tachyon://host136:19998/hdfspath");

用spark在tachyon上建hive表：

CREATE EXTERNAL TABLE `test4`(
  `aaa` string,
  `ccc` string,
  `bbb` string)
PARTITIONED BY (
  `day_id` string,
  `hour_id` string)
ROW FORMAT SERDE
  'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
STORED AS INPUTFORMAT
  'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
  'tachyon://host136:19998/tmp/storm2'
