I ever faced this error in one of my environments. That env has several streaming cubes building every couple mintues, so lots of files accumulated in the metadata table. Run a metadata cleanup solved that problem (follow the cleanup step in https://kylin.apache.org/docs20/howto/howto_backup_metadata.html).
You also need check HBase's status to see whether there is offline regions. 2017-08-07 23:29 GMT+08:00 bk_180 <[email protected]>: > Hi all, > > We are facing some errors due to timeout exception. > > {"url":"http://<masternode>:7070/kylin/api/jobs/349d62e3- > 7748-46ee-8009-3085726b5933","exception":"java.lang.RuntimeException: > org.apache.kylin.job.exception.PersistentException: > java.net.SocketTimeoutException: callTimeout=60000, callDuration=63012: > row > '/execute/349d62e3-7748-46ee-8009-3085726b5933' on table 'kylin_metadata' > at > region=kylin_metadata,/dict/VIEW_CREDITO/COD_PROMOTOR/ > a61c83e7-01e7-4971-9539-dd5c7ed07dff.dict,1500376865680. > 301b695304237ff0d1a7774bbff83b67., > hostname=<node>,16020,1501960877256, > seqNum=163046"}--------------------------------------------- > ------------------------- > > We have already changed the following properties > hbase.client.scanner.timeout.period and hbase.rpc.timeout to 600.000.
