Hi,
Finally, I found this in org.apache.kylin.storage.hbase.HBaseResourceStore:
```
private StorageURL buildMetadataUrl(KylinConfig kylinConfig) throws
IOException {
StorageURL url = kylinConfig.getMetadataUrl();
if (!url.getScheme().equals("hbase"))
throw new IOException("Cannot create HBaseResourceStore. Url not
match. Url: " + url);
// control timeout for prompt error report
Map<String, String> newParams = new LinkedHashMap<>();
newParams.put("hbase.client.scanner.timeout.period", "10000");
newParams.put("hbase.rpc.timeout", "5000");
newParams.put("hbase.client.retries.number", "1");
newParams.putAll(url.getAllParameters());
return url.copy(newParams);
}
```
Is this related to the timeout error? Why these params are hard coded instead
of reading from configuration, is there any workaround for this timeout error?

Hi, kylin users,
I encountered an strange timeout error today when buiding a cube.
By "strange", I mean the "hbase.rpc.timeout" configuration is set to 60000 in
hbase, but I get "org.apache.hadoop.hbase.ipc.CallTimeoutException: Call
id=8099904, waitTime=5001, operationTimeout=5000 expired" errors.
Kylin version 2.2.0, runs on EMR, and it runs wihtout error for about half of a
month, suddenly it not work, the current cube is not the biggest one.
I am wondering where should I look, any help is appreciated.
The traceback from log:
