Especially if it is at the query level. Could aggregate this at the daemon level as well. > LLAP: Consider adding counter to indicate number of times LLAP IO reader got disabled > ------------------------------------------------------------------------------------- > > Key: HIVE-15943 > URL: https://issues.apache.org/jira/browse/HIVE-15943 > Project: Hive > Issue Type: Bug > Components: llap > Reporter: Rajesh Balamohan > Priority: Minor > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
