Spark遇到的报错和坑

1. Java版本不一致，导致启动报错。

# 解决方法：
在启动脚本最前边添加系统参数，指定Java版本
export JAVA_HOME=/usr/java/jdk1.8.0_181-amd64/jre

2. Spark1和Spark2并存，启动时报错。

# 在SPARK_HOME中指定启动的spark版本
export SPARK_HOME=/data01/opt/cloudera/parcels/SPARK2-2.3.0.cloudera3-1.cdh5.13.3.p0.458809/lib/spark2

3.缺少Hadoop依赖包

解决方法：
#添加Hadoop的classpath到SPARK_DIST_CLASSPAHT中
export SPARK_DIST_CLASSPATH=$(hadoop classpath)

4. 报错信息：java.lang.Error: java.lang.InterruptedException: sleep interrupted

解决方法：
    将 ssc.awaitTerminationOrTimeout(1000)
    改成ssc.awaitTermination() 即可

5. 报错5

FAILED: Execution Error, return code 3 from org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask

解决方法:
    set hive.mapjoin.localtask.max.memory.usage=0.99;
    set hive.auto.convert.join=false;
