Hi All, I have done upgrade from HDP 2.4.3 to 2.6.1, where my hive jobs are running but i cant get the Full log information of those hive jobs i.e. Map and Reduce logs are missing and i can only see the Query execution time and Application job id and others. It reflects with "log4j:WARN No such property [maxFileSize] in org.apache.log4j.DailyRollingFileAppender". While executing the hive command also i'm getting the same warn. I have tried with setting maxFileSize to 256 in hdfs log4.j configuration, yarn log4.j configuration, Hive log4.j configuration but it reflects the same. Please guide me how to ignore this error and bring back all my log information. Regards, Mathivanan
