kylin.metadata.url with hbase namespace problem

    XMLWordPrintableJSON

    Details

      Description

      we want to change hbase namespace from "default" to "ALALEI",for security reason

      env:
      Kylin downloaded from https://dist.apache.org/repos/dist/release/kylin/apache-kylin-1.2/apache-kylin-1.2-bin.tar.gz
      Hbase: 0.98.16.1 from community

      conf/kylin.properties
      kylin.metadata.url=ALALEI:kylin_metadata@hbase

      when building sample cube,step 1 hangs on:
      FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:java.lang.IllegalArgumentException: Pathname /user/alalei/kylin/ALALEI:kylin_metadata/kylin-c39f5ba8-37cf-4da9-a995-b71fce988259/kylin_intermediate_kylin_sales_cube_desc_19700101000000_20160201000000_c39f5ba8_37cf_4da9_a995_b71fce988259 from /user/alalei/kylin/ALALEI:kylin_metadata/kylin-c39f5ba8-37cf-4da9-a995-b71fce988259/kylin_intermediate_kylin_sales_cube_desc_19700101000000_20160201000000_c39f5ba8_37cf_4da9_a995_b71fce988259 is not a valid DFS filename.)

      the above kylin.metadata.url with namespace works fine with hbase operation,and i can see hbase new tables created under namespace "ALALEI"

      the error happens in ./job/src/main/java/org/apache/kylin/job/JoinedFlatTable.java with function generateCreateTableStatement,where the second parameter storageDfsDir defined in getMetadataUrlPrefix from ./common/src/main/java/org/apache/kylin/common/KylinConfig.java

      hdfs don't allow special colon in hdfs url path,so hive related create table ddl with location can't be executed
