Support LocalPartitionReader read partition by chunkOffsets when enable optimize skew partition read
Why are the changes needed?
In CELEBORN-1319, we have already implemented the skew partition read optimization based on chunk offsets, but we haven't implemented the local partition read. This pull request aims to implement the local partition read.
Does this PR introduce any user-facing change?
When
celeborn.client.adaptive.optimizeSkewedPartitionRead.enabledset to true, when read local skew partition files, will read data by chunk offsets.How was this patch tested?
Current uts and cluster test.
