Review comment:
if we only have log files. inMemoryFileIndex.allfiles will be empty,
since spark will filter .log
fsView.getLatestBaseFiles.iterator().asScala.toList.map(_.getFileStatus.getPath.getParent)
will return a empty partitionPaths. then buildFileIndex will return
HoodieMergeOnReadFileSplit, nothings will be read
