I'm getting this error most of the time, but every now and again the querry works and returns the data requested.

Querry:SELECT time, lat, lonFROM state_vectors_data4WHERE time > 1693785764;

Error:ERROR: Disk I/O error: Failed to open HDFS file hdfs://nameservice1/user/opensky/tables_v4/state_vectors/hour=1691424000/(2): No such file or directoryRoot cause: RemoteException: File does not exist: /user/opensky/tables_v4/state_vectors/hour=1691424000/(:66)at (:56)at (:2157)at (:2127)at (:2040)at (:583)at (:94)at (:377)at $ClientNamenodeProtocol$()at $Server$(:617)at $(:1073)at $Handler$(:2281)at $Handler$(:2277)at (Native Method)at (:422)at (:1920)at $(:2275)

Typically, a specific recent hour (or several) do not work. We'll fix it, of course. In the meantime, if you leave those out of the query it works.
