      Description

      https://github.com/apache/hive/blob/master/llap-server/src/java/org/apache/hadoop/hive/llap/io/api/impl/LlapRecordReader.java#L174

      Sometimes, due to schema evolution checks, LLAP IO reader could be skipped and reader falls back to inputformat's recordreader. Currently this information is embedded in logs. It would be helpful to surface this in counters which can be used for query analysis.
