I discussed it offline with @tomscut yesterday and confirmed that it was a problem that occurred when reading ROW_INDEX. We tried to use `orc-tools meta --rowindex X`, and the tool will also report an error. `StripePlanner.readRowIndex(StripePlanner.java:404)` https://github.com/apache/orc/blob/310fb43fc69a0942f46dd4de3f648727d984e535/java/core/src/java/org/apache/orc/impl/reader/StripePlanner.java#L403-L404 --- Here, we may use `spark.sql.orc.filterPushdown=false` to avoid reading `ROW_INDEX` for recovery of data in Spark. As for why the data is corrupted, it is still suspected that it is caused by HDFS EC. cc @dongjoon-hyun -- This is an automated message from the Apache Git Service.
