Hi,
It looks strange. From
https://github.com/apache/kylin/blob/0d5f85b0a40c301134122de927204a0d17ad65fa/core-common/src/main/java/org/apache/kylin/common/persistence/ResourceStore.java#L89,
we can infer the field “clsName” is Line 89 is null in your env, which should
be impossible. Because from your log, matadata url is set to
kylin_metadata@hbase.
public Map<String, String> getResourceStoreImpls() {
Map<String, String> r = Maps.newLinkedHashMap();
// ref constants in ISourceAware
r.put("", "org.apache.kylin.common.persistence.FileResourceStore");
r.put("hbase", "org.apache.kylin.storage.hbase.HBaseResourceStore");
r.put("hdfs", "org.apache.kylin.common.persistence.HDFSResourceStore");
r.put("ifile",
"org.apache.kylin.common.persistence.IdentifierFileResourceStore");
r.put("jdbc", "org.apache.kylin.common.persistence.JDBCResourceStore");
r.putAll(getPropertiesByPrefix("kylin.metadata.resource-store-provider."));
// note the naming convention --
http://kylin.apache.org/development/coding_naming_convention.html
return r;
}
I wonder if you could provide us with more message for detailed analysis, such
as kylin.properties and full kylin.log. Thank you.
If you use Kylin for the first time and you are familiar with Docker, maybe
you can run a docker container to have a technical preview. Please refer to
http://kylin.apache.org/docs/install/kylin_docker.html.
