> We meet this annoying problem many times when the {{sharedStateDir}} in
> checkpoint path exceeded the directory items limit due to large checkpoint:
> {code:java}
> org.apache.hadoop.hdfs.protocol.FSLimitException$MaxDirectoryItemsExceededException:
> The directory item limit of xxx is exceeded: limit=1048576 items=1048576
> {code}
> Currently, our solution is to let {{FsCheckpointStorage}} could create
> sub-dirs when calling {{resolveCheckpointStorageLocation}}. The default value
> for the number of sub-dirs is zero, just keep backward compatibility as
> current situation. The created sub-dirs have the name as integer value of
> [{{0, num-of-sub-dirs}})
