Running Shark Locally 及可能出現的問題

Shark本地安裝 

1.下載scala 
wget http://www.scala-lang.org/files/archive/scala-2.9.3.tgz 
最新有2.10.2.tgz文件 
tar xvfz scala-2.9.3.tgz 

2.下載shark and hive壓縮包 
wget http://spark-project.org/download/shark-0.7.0-hadoop1-bin.tgz (cdh3) 
tar xvfz shark-0.7.0-*-bin.tgz 

3. 配置環境變量 
cd shark-0.7.0/conf 
cp shark-env.sh.template shark-env.sh 
vi shark-env.sh 
export HIVE_HOME=/path/to/hive-0.9.0-bin 
export SCALA_HOME=/path/to/scala-2.9.3 

4.測試數據 
CREATE TABLE src(key INT, value STRING); 
LOAD DATA LOCAL INPATH '${env:HIVE_HOME}/examples/files/kv1.txt' INTO TABLE src; 
SELECT COUNT(1) FROM src; 
OK 
500 
Time taken: 2.149 seconds 
沒有了hive中的mr，速度快了不少 
CREATE TABLE src_cached AS SELECT * FROM SRC; 
SELECT COUNT(1) FROM src_cached; 

安裝過程中可能出現的問題及解決 

1.CREATE TABLE src(key INT, value STRING); 
FAILED: Error in metadata: MetaException(message:Got exception: org.apache.hadoop.ipc.RPC$VersionMismatch Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version 

mismatch. (client = 61, server = 63)) 
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

reason：Hadoop版本與SHARK的Hadoop core jar包版本不一致引起的。 
解決：將${HADOOP_HOME}/hadoop-core-*.jar copy 到${SHARK_HOME}/lib_managed/jars/org.apache.hadoop/hadoop-core/目錄下面，rm原來的hadoop-core-*.jar 
重新進入Shark 

2.出現java.lang.NoClassDefFoundError

reason：CDH版本的缺少一個第三方包guava-*.jar 
解決：建一個目錄${SHARK_HOME}/lib_managed/jars/org.apache.hadoop/thirdparty，拷貝${HADOOP_HOME}/lib/guava-r09-jarjar.jar到這個目錄 
重新進入Shark 

3.show tables出現問題 
Failed with exception java.io.IOException:java.io.IOException: Cannot create an instance of InputFormat class org.apache.hadoop.mapred.TextInputFormat as specified in 

mapredWork! 
reason：缺少hadoop-lzo-*.jar引起的 
解決：建一個目錄${SHARK_HOME}/lib_managed/jars/org.apache.hadoop/lib, 拷貝${HADOOP_HOME}/lib/hadoop-lzo-*.jar到這個目錄 
重新進入Shark 

4.SELECT count(1) FROM src_cached出現問題

reason：java1.6版本低，需要安裝jdk7. 
解決：安裝jdk7, JAVA_HOME指向新的JDK7,問題解決 
tar xvfz jdk-7u25-linux-x64.tar.gz -C /usr/java/ 
export JAVA_HOME=/usr/java/jdk1.7.0_25 
export CLASSPATH=/usr/java/jdk1.7.0_25/lib
