阿里云EMR3.2 hbase/phoenix客户端BUG

错误现象：

1. 今早在EMR3.2的生产新集群上执行导出操作，h  org.apache.hadoop.h .mapreduce.Export safeclound.tb_ammeter /backup/tb_ammeter 1 1531843200000 1532016000000

2. 错误表现：

执行job任务显示：

2018-07-19 17:07:26,113 INFO [main] mapreduce.Job: Task Id : attempt_1529895044112_7775_m_000002_1, Status : FAILEDError: java.io.IOException: Cannot create a record reader because of a previous error.

然后查看日志：

Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.h .ipc.controller.ServerRpcControllerFactory

....

解决方法（经联系阿里工程师，提供以下方案）：

1. 创建客户端使用的h 配置

> mkdir /tmp/h -client-conf

> cp /etc/ecm/h -conf/* /tmp/h -client-conf

> vim /tmp/h -client-conf/h -site.

删除phoenix相关的配置，保存：

h .rpc.controllerfactory.class

h .master.loadbalancer.class

h .region.server.rpc.scheduler.factory.class

h .coprocessor.master.classes

2. 执行命令时指定使用客户端配置

h --config /tmp/h -client-conf org.apache.hadoop.h .mapreduce.Export safeclound.tb_ammeter /backup/tb_ammeter 1 1531843200000 1532016000000
