i resolve the problem .
i check my hdfs log and find some information below:

then i realized probably my config about Compression algorithm is wrong
so i disabled Compression algorithm of snappy by delete relative config.
To disable compressing MR jobs you need to modify
$KYLIN_HOME/conf/kylin_job_conf.xml by removing all configuration entries
related to compression(Just grep the keyword “compress”). To disable
compressing hbase tables you need to open $KYLIN_HOME/conf/kylin.properties
and remove the line starting with kylin.hbase.default.compression.codec.
finally, i restart my service and it works well.
