> This code in {{AbstractTableFileSystemView}} incurs a mkdir operation which is an anti-pattern, as reader should not incur write operation:
> protected FileStatus[] listPartition(Path partitionPath) throws IOException {    try {
>       return metaClient.getFs().listStatus(partitionPath);
>     } catch (IOException e) {      // Create the path if it does not exist alreadyif (!metaClient.getFs().exists(partitionPath)) {
>         metaClient.getFs().mkdirs(partitionPath);
>         return new FileStatus[0];
>       } else {        // in case the partition path was created by another caller        return metaClient.getFs().listStatus(partitionPath);
>       }
>     }
>   }
