1、spark汇聚失败
出错原因，hive默认配置中parquet和动态分区设置太小
hiveContext.setConf("parquet.memory.min.chunk.size","100000") hiveContext.setConf("hive.exec.max.dynamic.partions","100000")
2.hive数据入hbase报错
出现报错原因：
executor_memory和dirver_memory太小，在增大内存后还会出现连接超时的报错
解决连接超时：spark.network.timeout=1400s
在此问题解决后，还是会有以下报错

出现以上报错是资源不足导致的。需设置永久代
spark.driver.extraJavaOptions="-XX:PermSize=2g -XX:MaxPermSize=2g"
