Hi,shi

Thank you all.

主题: Re: kylin problem with metadata
Is there any other error before this?
When submitting a hadoop job, Kylin will dump the metadata to a local temp folder and then send it to slave nodes via Hadoop distributed cache; Please check whether that folder was cleanned up unexpectly, or whether the account that running Kylin has the write permission on the tomcat temp folder.
We didn't see this error before, it should be an environment specific issue.
