Error: Failed to find metadata store by url: kylin_metadata@hbase
Hi Team,
I am new to Kylin. I have installed Kylin 2.6.3 using below link.
http://kylin.apache.org/docs/install/
When I am trying to start Kylin getting below exception.

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.
