### What changes were proposed in this pull request?
Avoiding multiple accesses to HDFS when retrieving indexes in
DfsPartitionReader
### Why are the changes needed?
This optimization method improves read performance by reducing the number of
interactions with HDFS, merging multiple small I/O operations into a single
large I/O operation. Especially when index files are small, the strategy of
reading the entire file at once can significantly reduce the number of I/O
operations.
