Hi ORC team
Recently i have a case, not sure if it is possbile to restore the orc file. now ask for help, Steps to reproduce. Step 1、we have a hive table A, which stored as orc, we have data（file a,file b,file c...) in tableA, Step 2、we read data files（file a,file b,file c...）with text format by spark engine and rewrite data back (file x,file y,file z...) with text format to tableA, Step 3、now tableA is serialized with orc, but the files are text format, which makes it impossble to read the data by text or orc. ps : data in table A is non-reproduce data and cannot be backtrack from origin source. I wonder if it possible to restore the data, or we can do to restore the data by reconstruct the orc files. Any help or suggestions will be appreciated. Best Regards.
