h2. Cause Analysis
# job.getConfiguration() at HFileOutputFormat3.java:530 ,I found this method
may be get wrong result ,because I config “hbase.fs.tmp.dir” in hbase-site.xml
!image-2020-08-06-18-58-00-355.png!
# job.getgetConfiguration(), this method will call
org.apache.kylin.storage.hbase.HBaseConnection#newHBaseConfiguration
-->call org.apache.kylin.common.util.HadoopUtil#healSickConfig
!image-2020-08-10-19-38-28-913.png!
# some other information https://issues.apache.org/jira/browse/KYLIN-953
# fs.deleteOnExit(partitionsPath) at HFileOutputFormat3.java:536，this method
do not work ，because the JVM won't shut down unless Kylin stop. So tmpfile
won't be cleaned up
