Subject 答复: kylin problem with metadata
Date Tue, 12 Jan 2016 07:14:49 GMT
Hi,shi

	I think there may be something wrong with my hbase cluster, so  it stopped at "dump the metadata
to local folder", I am repairing hbase.
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.
