@vinothchandar @bvaradar : need your help here. This patch is to avoid a direct fs call within log file reader. the call of interest is used in detecting schema from log file and we do reverse reading and so we do fs.getFileStatus(logFile).getLenth(). I tracked back the call and realized that within HoodieRealtimeInputformatUtils. We have a file slice from which we get log files, at which juncture I fetch the log file length and carry that info all the way to RealTimeSplit and use it in LogReaderUtils and HoodieLogFileReader. This fix worked well until recently we landed [mor-incremental support](https://github.com/apache/hudi/commit/a40ac62e0ce7ec807a00803d23ed223d7c607459) for hive. If not for this recent patch, this PR was in good shape. Specifically, the [HoodieLogFile from fileSlice](https://github.com/apache/hudi/blob/2d362af00ae61ab76ff45fd83f142d3af4bd0909/hudi-hadoop-mr/src/main/java/org/apache/hudi/hadoop/realtime/HoodieParquetRealtimeInputFormat.java#L201) has file size set to 0. My assumption is that, HoodieLogFile object will always have file size set. So, my question is: is there a bug somewhere on this end. or we can't assume length will always be set for HoodieLogFile. need pointers from you folks on this end. -- This is an automated message from the Apache Git Service.
