解决办法

1.1 服务端配置
在运行load数据的节点上的/etc/hbase/hbase-site.xml（这里就是服务端）里添加如下配置：

<property>
<name>phoenix.schema.isNamespaceMappingEnabled</name>
<value>true</value>
</property>

1.2 客户端配置

在Phoenix的bin目录下hbase-site.xml（这里就是客户端）里也需要有这个配置

1.3 一点疑惑

明明cm上hbase的这个配置是已经为true了，但总是在第一点提到的这个文件里的这个配置总是会被冲掉。目前还不知道原因。

注：执行命令为：
hadoop jar phoenix-4.8.0-cdh5.8.0-client.jar org.apache.phoenix.mapreduce.CsvBulkLoadTool --schema phoenix440000 --table INCRV8_MIO_LOG --input /user/hdfs/mio_log.csv --delimiter '$' --ignore-error
