> kylin版本从3.0.2更新到3.1.1，还是用原来的元数据。
> 发现在EMR的core节点中有大量的kylin-coprocessor文件生成，见附件屏幕快照1，占用了大量的空间，导致hdfs文件系统可用空间变少。路径为/mnt/tmp/hbase-hbase/local/jars/tmp
> 查询官方文档 [http://kylin.apache.org/docs/howto/howto_update_coprocessor.html]
> 执行如下命令仍然不好用，日志信息见附件
> -------------------------

> {{$KYLIN_HOME/bin/kylin.sh
> org.apache.kylin.storage.hbase.util.DeployCoprocessorCLI default all}}
> {{-------------------------}}
> 同时发现kylin元数据
> kylin_metadata/coprocessor/下有大量的kylin-coprocessor-3.1.1-*.jar文件，见附件屏幕快照2
>
> 是什么原因导致的这种现象？
> 如何才能在/mnt/tmp/hbase-hbase/local/jars/tmp路径下不再产生大量的文件？
