> {color:#ff0000}hbase-ns-test{color} is the nameservice of HDFS which is used by HBase.
> In our kylin environment, HBase and MR/HIVE use different HDFS clusters.
> {code:java|title=CubeHFileJob.java|borderStyle=solid}
> // use current hbase configuration
> Configuration configuration = new Configuration(HBaseConnection.getCurrentHBaseConfiguration());
> merge(configuration, getConf());
> {code}
> "getConf()" contains only the HDFS configuration of MR, and "configuration" contains the HDFS configuration both HBase and MR. See: [HBaseConnection#addHBaseClusterNNHAConfiguration()|https://github.com/apache/kylin/blob/d23d2bddab3263d39059492b91f71d8091198057/storage-hbase/src/main/java/org/apache/kylin/storage/hbase/HBaseConnection.java#L205]
> So "merge(configuration, getConf())" will lead to HBASE's HDFS configuration to be covered. Mainly parameter "dfs.nameservices"
